I have been using itunes since friday night w/o problems. Today while ripping a new cd...it frooze up about half way through. I restarted my computer and now when I try to open itunes I get an error message that reads.." itunes music library cannot be read because it does not appear to be a valid library file" I can't get past this message. I even uninstalled itunes and reinstalled...still get it!! I just upgraded to xp this weekend, but itunes ran fine the first 5 times. Anyone familiar?
