Hi, I just got Jaguar for my Ruby iMac. It has worked great until recently when I accidentally deleted a folder on my desktop that contained all of my games and homework and some pictures . Now the address book, iPhoto and the Mac help center apps don't work. They just bounce in the dock and then stop. How do I get them to work again. Another weird thing is that it most of the photos I had on iphoto are still there and I can still get the e-mail addresses in the Mail app. I am puzzled why this happened since I don't think that I had any of the deleted files had anything to do with those apps running. If someone could help me I would apprieciate it greatly! Thanks!
