okay EVERYONE with this problem. After 2 hrs on the phone with apple support and NO HELP it was a combination of turingtest2's first post on page one of this forum and my own twisting and turning that I figured it out.
Im posting because I am an artist, radio dj, and manage a label- So I was ready to kill someone when vamous,, all my playlists music etc up and vanished..
When itunes11 updates check:
itunes>
preferences>
advanced>
(it will show you the location it is pulling from for your library)
In that folder it will display "itunes library.itl" < that guy is probably showing a size of KB...
So what turingtest2 reccomended (on the first page of this forum) was to label that file as "itunes library (corrupt).itl" and to in your finder search "previous itunes libraries" and in that folder you will see probably several other "itunes library (and the date here).itl"s
You would then want to copy the most recent dated "itunes library (date here).itl" paste it in the location your itunes is pulling from and rename it "itunes library.itl" (aka take the date out)..
So i did that and it wasn't working....
It was changing what I was pasting in, back to the "itunes library (corrupt).itl KB size file...
Until I just deleted the "itunes library (Corrupt).itl" >
Once I deleted that and pasted in the "previous itunes libraries"s "itunes library (date here).itl" and took out the date.. It worked.
Long story short, just delete that "itunes library.itl" its pulling from>
Copy the most recent dated "itunes library (date here).itl" paste it in the location your itunes is pulling from and rename it "itunes library.itl" (aka take the date out)..
Hope this helps.. im not tech savy at all and apparently neither were the ppl at itunes and the 5 specialists I went through until I FIXED THE PROBLEM with the help of turingtest2 so thank you to him/her whoever they are...
if you are still just confused.. look at turingtest2 's post with pictures on page 1 of this forum and what i wrote should make sense..
