my sister just got a new sony laptop for xmas. and i installed itunes, and then ran all the updates, and now it keeps crashing whenevr i try to open it.

other programs are also crashing before they start, eg yamipod, and the tv card program. any ideas?

Do the programs not even open, or open and then crash with some error. If so, what are the errors? Have you checked the event log?

they aren't even opening. doesn't seem to be any errors in the event logger when i have a look. only a norton problem, but i'm trying to remove it anyway. and i used the system restore to go back to before all the updates and itunes etc are still crashing
