I am part of the developer community, and I have iTunes 10.5b3 installed on my Mac, I guess I must of forgotten, however today I open iTunes and I get a message that 'This copy of iTunes will expire in xx hours' at the moment its 47 hours. I download the latest version of iTunes, which is 10.5, attempt to install it, system says there is a newer version, won't install. Suggestions? At this point I am considering, backing up iTunes, removing 10.5b3 and installing the latest version, I don't see an alternative? Thanks.
