iTunes library on network drive, no longer able to download from store

I'm thinking it may be possible that this is related to the update for iTunes that came out last week.

Before that I was easily able to download items from the iTunes store into the media folder on my network drive.

How would I go about reverting back to the previous version of iTunes to test this out?

I don't really feel comfortable messing with the permission settings. But I can manually add movies and music to iTunes and it automatically makes a new folder and copies the file into it. So I don't think it's a permissions problem.

That other article you provided doesn't give any way to get the previous version of iTunes. Those instructions say to go back to www.apple.com/itunes/download and it only has the latest version available.

I don't think anything has changed other than the update to iTunes. I've been running it this way for about 2.5 months and regularly downloading purchased movies. The last movie I downloaded was on 4/11/15 and there was no problem at all. I first discovered the problem on 4/15/15 trying to download some digital copies of a Blu-ray set I purchased.

I'm going to try removing iTunes and install the prior version.

I followed the instructions and uninstalled everything and deleted the folders that I had, rebooted and installed iTunes 12.1.1.4. Something may not have worked correctly because when it launched it already had loaded my existing library (from the network drive).

I went ahead and tried to download a song but got the same error as before.

As for creating a new library there is no way I am re-downloading everything I own. Maybe there is a way to create a new library and just move the existing one into it???

Uninstalling and reinstalling iTunes shouldn't affect your library, although sometimes you cannot downgrade to an older build without restoring an older version of the database. So far all versions of iTunes 12 seem to use the same library.

Under Edit > Preferences > Advanced click Reset Cache, and delete the folder called Downloads that can be found inside your media folder. Try again. Any change?

No, that didn't make any difference.

I had tried that already. I'm thinking about moving my library to a USB drive. The network drive is much bigger so I'd rather use that though.

Is the whole library on the network drive, or just the media folder? Is it a NAS or a shared folder on another Windows machine? A USB connected drive as your primary library with the network drive as backup may be a more robust solution. If you library files are on the system drive see Make a split library portable.

I had the entire library on the network drive. At one time I used it with just the movies on a drive that was plugged into my router but that was a hassle. So I bought the 4TB network drive hoping this would be an easier solution and I could store everything on it.

It had work fine for a while but I do not know what happened. Nothing I tried worked. I successfully moved my library to my USB 3.0 drive and it is working just fine. I am able to download from the iTunes store now.

Now, I did discover that some movies were missing but I can re-download them easily.

What I don't understand is that if I view my purchases in the iTunes store and tell it to show only movies that are not in my library it shows a whole lot of things that ARE in my library.
