Hi, I'm on Lion 10.7.4 and trying to install the latest iTunes 10.6.3 through Software Update. Software update gives me the error, "File cannot be verified. It may be corrupted etc etc" on www.apple.com/itunes the Download button seems "dead". Pressing it yields nothing. What's going on, is Apple currently pushing out a new version, and that's why it doesn't work, or what?
