ok. Whenever I try to get online a message comes up and says "You have an important message from xbox live. Would you like to start acount management?" and the two options are "start acount management" and "continue offline", I want to do neither. But when I click on acount management, there's no message that I can find. I was wondering if anyone knew how to fix this because I woukd really like to get online on halo 2.
