Q: missing loops in Logic 10.2.1 and download failure

Thank you. This helped me find "Reindex All Loops".  I ran it and now the greyed out loops disappeared completely.

For example in Logic 9 I always was able to select 'Pig Grunt', and "Amazing Spoken Word" and many others from the Loop Browser.

At some point (I don't know what point)  in Logic X those two loops and dozens and dozens of loops became greyed out.

Now, after running 'Reindex All Loops' , the loops that were greyed out yesterday are completely absent from the loop browser.

Since I had these loops before I'm pretty sure I still have them somewhere, maybe on a Time Machine backup if they've been deleted

from my hard drive.  Maybe they were deleted when I uninstalled Logic 9? Or are the missing loops all from GarageBand maybe?

Yesterday I was trying to demo Garage Band (which I NEVER use) to a student, and GarageBand would not run, gave a missing loop index error.

I will try Art of Sound's suggestions to complete the download of 'Download All Available Sounds'.  Maybe my missing loops are in that download?

quick summary:

Logic 9 worked great for a long time.

In November 2015 I upgraded to Logic Pro X, love it.

Yesterday I upgraded to 10.2.1.

AT SOME POINT,dozens and dozens of loops went missing from the Loop Browser.

My goal is to download ALL additional content and have ALL my loops available, including Pig Grunt and all the ones I had in Logic 9.

I've been able to download ALMOST all additional content.  Still stuck on 'Download All Available Sounds.'   Working on the 5 sec remaining issue on that.

That is what I'm working on, and thank you again for any help.

Art of Sound, thank you.....I created a new Sys Admin account, restarted, signed on with the new Sys Admin account,  started up Logic Pro 10.2.1, waited for it to scan all my plug-ins, then tried 'Download All Available Sounds'. I got exactly the same hang up at 5 seconds: "Logic Pro X was not able to complete the download. Check your internet connection and try downloading again."  As I said, this hang up is not because of an internet connection dropping.  As you said, it's probably a permission problem.  It NEVER asks me to enter my password like it did on most of the other 'Additional Content' downloads I successfully did yesterday.  This is the only content download that fails - consistently. I don't know squat about permissions. I only ever sign on as the admin, one computer, one user - me.

The option to 'Download All Available Sounds' brings up a download of something called 'Complete Sound Library', showing as a measly 18.3MB.

I want to have ALL additional content available is why I keep trying to download it.

QUESTION: Is there a direct link anywhere to download this content ("Complete Sounds Library")?

QUESTION: What is inside the 'Complete Sounds Library'?

QUESTION: What does the new option 'Reinstall Sound Library' do?

P.S.  the "Amazing" spoken word loop is just a guy saying 'Amazing'. There was always whole little group of spoken word loops like "Oh Yeah", etc etc... All missing now.  I used "Amazing" on one of my very first Logic 9 projects. I guess I will hunt for the loops I know are missing, on my Time Machine, to see if that helps me find them.  Also I would swear I used to have a loop category called 'Animals', gone now.  I have created dozens of playful recordings with young students,  in Logic 9 and Logic 10 (before yesterday) using Dog Bark loops.  Now those are all gone. My unverified hunch is that the loops I am talking about, that are now missing,  came from GarageBand and I have either deleted them along with uninstalling Logic 9, or maybe 10.2.1 has purposefully left them out, or they are just misplaced for some reason I don't know.

WHY SOME LOOPS ARE MISSING (THEORY)

OK I found the missing loops in my Time Machine from before I installed Logic Pro X.

In my Logic 9, which was the full-blow 'Studio' version including 'Soundtrack Pro', etc, etc, it had a folder within Apple Loops called Soundtrack Pro.

It has a similar folder for GarageBand loops. For example if your Loop Browser DOES show 'Asian Gamelan 07' but does NOT show 'Asian Gamelan 01',

you have the same problem I've just had - your GarageBand loops that you had in Logic 9 are GONE when you update to 10.X.  (Theory).  Or they are GONE because you uninstalled Logic 9 (Alternate Theory).

I think all my missing loops are found now.  Later I will copy those old folders from Time Machine and try to install them into 10.2.1's Loop Browser, that should work fine I would think.

I think  Logic 10.2 or Logic 10.2.1  intentionally deleted those folders upon updating. (Theory 1)

The Folder names are different now. The Soundtrack Pro folder within 'Apple Loops' is gone.  I can detail out the relevant folder names  later....  Or possibly

I caused these folders to disappear when I uninstalled Logic 9?  (Theory 2) I do not know, but I am glad I found my missing loops on my Time Machine!!!!!

ANSWER to Art of Sound Question: The 18.3MB download called 'Complete Sound Library' is what is downloaded (on my system) when I select "Download All Available Sounds".

HOW TO FIX DOWNLOAD FAILURE at 5 seconds:  I don't know yet.

Thank you....This procedure will help others. In my case I deleted LP9 about a week ago, I'm not likely to re-install it.

Since finding my all missing loops on a Time Machine backup, I have imported them into LPX's loop browser no prob. Yay!

Now that the missing loops are back in service, I don't care exactly HOW or WHEN they went missing, but I know it was either when I deleted Logic 9, or it was something Logic X did.

All I seem to be missing now is the measly 18.3MB of 'Complete Sound Library'

which is downloaded when I selected 'Download All Available Sounds' in Logic Pro 10.2.1

My system downloads all 18.3MB out of 18.3MB of it,  then hangs at 5 seconds without asking for a password,

giving the inappropriate message every time (and I've tried 20 times, so enough already with me trying): "Logic Pro X was not able to complete the download. Check your internet connection and try downloading again."  

I have no idea what's in that 18.3MB of 'Complete Sound Library', but I guess I can live on without it for now.

Since ALL of my other app and content downloads have downloaded and installed just fine thank you,

I have to suspect a bug in the code for this particular 'Complete Sound Library' download rather than the typical fixes for this

message like faulty internet connection, 'you need to try Ethernet', permission problems, etc. 

I tried booting my Mac in safe mode, since one user on this forum said that fixed this message for him.

But then Logic basically would not load in safe mode.  I got the pinwheel for 5 minutes and bailed out.

right, thanks.  Downloading etrecheck.com now.

maybe can get another year or two from my late 2008 macbook pro.

thanks for the detailed help!

Well at the end of the 2nd day, I ran "Verify Permissions" again, and "Repair Permissions" again, and "Verify Disk" again (in Disk Utility).

I tried 'Download All Available Sounds' for the 30th time in two days.  This time it DID ask for a password, and finish successfully.

I still don't know what's in that download.  It was only 18.3MB on my system.  Anyway it finished.

Many thanks again Art of Sound!!!!
