apparently it's nearly impossible to do because searching google only leads me to a bunch of usless programs and solutions that do nothing!
my itunes is all fucked up so i figured the obvious thing to do is delete it and reinstall. but for some reason you have to delete quicktime too, and that's where i'm running into problems. there's a corrupted folder in my quicktime directory so i can't delete it through the control panel OR manually. i don't even know if this'll solve my itunes problem but it seems like the safest bet right now. somebody point me in the right direction please!
