Logic Pro X: Upgraded to iOS High Sierra, now my apple/user loops are gone and makes the software crash/freeze

You may have run into this behavior due to the latest file system change.

Did you use to have Logic Pro 9 installed on this computer/system?

Try this if you recognize that your Audio Music Apps folder is an orphaned alias:

1. Quit Logic Pro X.
2. Delete the Alias ~/Music/Audio Music Apps then create a new folder on this location and give it the name Audio Music Apps.
3. Open the Terminal and paste this code followed by enter:
   

   open /.HFS+\ Private\ Directory\ Data?/

   
   - A new Finder window will reveal your hidden content.
   
4. Copy the content inside the 'dir_######' folder and paste it inside your new Audio Music Apps folder.
5. Relaunch Logic Pro X.

I never used Logic 9- but-

Since I upgraded- any time I open Apple loops it just freezes- nothing loads up. Actually I can still move stuff around and listen- doesn't work right or in real time. If I tell it to "index" it will index FOREVER. ok- so I only let it run about 4-5 hours, but i doubt I gave up too quickly. Also- I can not edit audio at all- I can "cut" with the scissor tool, but I can not delete audio. I can delete/remove a region- but not delete, or edit any of it. Those are the main things- Im sure i do not have full capabilities in other areas that I just don't regularly use though-

Any time I try to delete/stretch audio I get this message-

Error in parameter list / Not an existing volume, and no default volume / Bad positioning information / Bad drive number

Result code = -50

File = LogicSampleClip1

I have called apple- after a good hour of dude telling me various things to try out, he said he'd have to talk with the engineering division, and that could be 3-4 days. i called on the 4th day- still have no clue, just told me they're still trying and have not figured it out.

A few months ago they sent out an email to people who had registered the program with Apple. They said when the Fall update (High Sierra) is out, you would have to ONCE again buy Logic... but the latest digital version. I won't upgrade my OS.

***. I am already losing things... Losing my output audio. It is as if it expired!

I have the same issue and JUST posted!! Still looking for an answer.
