My sister completely freaked out earlier as she launched iTunes to find all her playlists and many purchased songs missing. It was 7.1 running on an iBook G3 (10.3.9). I tried all the obvious fixes (relaunch iTunes, restart computer, update to 7.1.1, restart again) Nothing. She did mention closing a progress window (something about downloading or updating something... she just closed it w/o reading it) that popped up as she launched iTunes. Help?
