I recently updated iTunes to 6.0.4 via Software Update. Now, when I launch iTunes, I get the license agreement. When I click "agree", the iTunes application menu bar appears, but then I get a dialogue box saying, "The iTunes application could not be opened. There is not enough memory available."
I've deleted all the plist files in my user home directory. That ended up letting iTunes run the welcome/set-up wizard, but when it came time to go to the library, I got the same error message.
I've tried to delete iTunes completely and reinstall with the a new copy from Apple's site. The installer takes me to a customized install, where I can choose from three options, iTunes being one. But they are all greyed out. If I do the simple installation, I'm told there is nothing available to install.
Wha' happened? Does anyone have any ideas and/or fixes?
