Like an idiot, I accidently downloaded the iTunes 4.5 upgrade. Immediately after, limewire starts refusing to open, and I get the "This application has unexpectedly quit" message. I have followed the directions in the iTunes forum to restore iTunes 4.2, and reinstalled Limewire and Quicktime 6.5.0, but limewire still won't open. I am not a computer genius, and would deeply appreciate any help y'all could offer.

Thank You
