Okay, so iTunes has gone loopy on my wife's old Macbook. I can't figure out what's going on. When we launch it, no music or playlists appear. It's like a clean install, but when I check the finder, the music files are all there. I've tried moving the iTunes folder away, letting iTunes create a new one and then replacing the new one with the folder that has all our songs, but it doesn't work.
Any idea what's going on?
