I have been playing Forza on xbox live for the past 2 weeks. Just recently, I haven't been able to sign in. When I select my profile, it signs in my profile then tries to login my xbox live name. It sits there for about 4 seconds, then just goes into the game with out giving me the 'xbox live sign-in successful' notification. I then don't have the ability to access my xbox live account at all. I don't get any errors or anything, just doesn't sign into xbox live. I know my account is still active because I am able to sign-in to xbox live in Halo2 and play online just fine. Can anyone offer any help? Thanks.
