I was doing several things at once on my iMac (ripping a DVD, on iChat video, etc) and my mac crashed. Now it won't open iTunes. I have a 500 gig music library and hundreds of playlists etc, so I'd hate to have to reinstall iTunes and lose all that. Is that what would happen if I reinstalled iTunes? I have Time Machine hooked up. Could I go into that and grab an iTunes prefs file from before the crash, and put that in the current system folder? Would that be something to try? Any help would be much appreciated!!
