When I re-downloaded i Tunes it found my music, but the playlists I worked on for three years were gone.
I have Back Blaze backup and I re-dl-ed i Tunes to get the XML Music file which is supposed to restore playlists by importing, but it didn't work.
The XML import process you went through is a method used to rebuild a library if you lose your i Tunes file. You may have a pseudo-recent backup of the i Tunes file in the i Tunes\Previous i Tunes Libraries folder.
You'll see they have dates on them based on the date you upgraded i Tunes.
I can see that one of the GWX tasks now no longer runs because of the registry setting the utility sets instead of the usual "system can not find the file specified" error (because I erased all the GWX files). That is where all your ratings, date added, playlists, skips and plays are stored.
I have all of the songs, all rated, and all working playlists on an i Pod.
Is there any way that I can get i Tunes to get the ratings and the working playlists back from the i Pod?
As long as your music was restored to the same location as your original location, everything in i Tunes should work now. So, this has now restored my music, podcasts and playlists.
BUT I no longer have the song ratings for each song, and the dates added are all wrong (they are from a couple of days ago when I reimported the music library).
