It may be a glitch because of the new Snow Leopard that has come out. I have both an iMac and a macbook and I've updated both the OS, iTunes AND Safari. I would try completely uninstalling (assuming you remember your password and username) iTunes, restart your macbook and redownload it. Sometimes iTunes is a bit buggy especially as they have updated it twice since Snow Leopard came out. If that doesn't work, I'd take it to an Apple Store and let them mess with it (make sure to make an appointment if you do that!)
