Aargh- I've just sat down after work to sit and relax to a bit of itunes relaxation and my entire library has gone, including purchases! Recent purchases the lot I've located my itunes music folder but importing each track again will be a nightmare plus there's loads of duplicates..is there any kind of system restore that I could use?? Also file vault..that pops up pretty regularly and seems to take forever to shutdown...what exactly is it doing and why?? Heeeelllllllllppp please!!!
