but if I am not logged in, or logged into a non-live account, I can navigate to the multiplayer, which then prompts me to select an xbox live account to play. Switching to my xbox live account then works and I can play.
Awkward. My main concern is if this is a sign of a bigger problem I want to take care of it while the xbox is still under warranty. (I only have this problem with COD WAW and MW2 btw.)
Thanks for your help
