I was upgrading from iLife 05 to 06 today, so I went and deleted all the 05 apps. but iTunes wouldn't delete because it said "ituneshelper" is in use. So I went to the ActivityMonitor and quit the process and then i was able to delete it. So then I installed iLife 06 and everythitng worked fine except for when i tried to open itunes, i got a message saying "Cannot be opened. iTunes is damaged or incomplete". So i tried totally deleting it again and then downloaded it off of apple.com. As I was going through the installation process, I got a message saying, "There is nothing to be installed." (as if iTunes was already on the computer or something, but it wasn't) Does anybody have any idea how to fix this? Anything would be greatly appreciated. thanks. bense.
