I was listening to music and suddenly my MBP froze, and the song I was listening to got stuck. I was forced to do a reboot. When I turned the computer back on, and opened iTunes, I got a warning message that the "Library was damaged" and that it was rebuilding it from somewhere. It reinstated all my playlists and music fine but all my extensive podcasts, audiobook and iTunes University information is gone! Is there any way to get it back? It took ages to assemble. I have both time machine backups and a series of 'previous iTunes libraries' available in my music folder but I don't really know what they do or how to enable an older library to see if it works. Can anybody help me? Thanks See attachments for my music folder.
