So my dad just got this brand spanking new computer from work, and his hard drive was copied to this one. So for msn, I go to it, I click on it (like usual) but when I sign in, it tells me "A newer version of MSN Messenger for Macintosh is available. You must download the newer version in order to continue using MSN Messenger. Would you like to do this now?" So I click yes. It downloads it, but I can't open it. It tells me the file is broken or something. So I go back and try to click no to the original question and therefore doesn't sign me in.
