So I was pi**ed that they removed the Album Art preview. I decided to downgrade. I renamed my iTunes folder within ~/Music. After deleting the 11 .app, I installed 10.7. I ran it and everything seemed fine. It was empty, of course. So I drag and drop all my files over from the old iTunes folder, except iTunes Library.itl. I copied the old one from the Previous folder, renamed it, and started iTunes. Everything looked as it was, even the window was resized like I had it -- but I had a popup window.
"An unknown error occured -42408"
I tried every single solution I could find on the internet and none of them helped it. I work in IT for a living so believe me when I say I tried everything. The only other solutions were upgrade iTunes (lol) or do a full Time Machine restore. I don't feel like restoring my entire computer tonight, so I decided to suck it up and reinstall iTunes 11.
What a ******* nightmare. I can't believe Apple would remove such useful features and not even give you the option to put them back. I guarantee you won't get them back, either. Apple doesn't have a great history of taking stuff away and giving it back. Really regretting my decision to try it out.
Oh yeah, and I had to fix my iPad with the fix provided above. Didn't help my error though. I couldn't authorize or deauthorize my computer. I want to see if I can deauthorize it with iTunes 11 and then try it with 10.7 but I've already messed around with it enough. I just want to have a good night. This pretty much wrecked it.
