After playing music via itunes all day, then updating my ipod, the blessed program decided to crash and come back with maybe 1/5 of all my songs and deleted my playlists. This is probably the 3rd time such a thing has happened with itunes. I figured an update was in order and plugged into the internet to do just that. Since the mac is never connected, quite a few programs came up needing updates. I agreed and let it do it's thing. After all was done I rebooted only to get no further than the grey apple plus the spinning wheel screen. No keys responded, the disc drive wouldn't open, nothing. Had to unplug to turn off. Tried rebooting 3 or so more times, left it on for a few hours hoping it would fix itself. Still nothing. There is currently nothing but music and a few pictures on the hard drive. No video or much else saved. Please help. I didn't switch to mac for any other reason than to avoid pc type problems, like freezing and viruses, and here I am with a bigger problem at hand. Any and all advice is greatly appreciated!
