So I return from dinner to play some Black Ops. So I go to dashboard from Modern Warfare 2, and I notice it says my account has been disconnected from Xbox live. No problem, I test connection and everything turns out fine. So I attempt to sign back in and it gives me the normal red x connection problem popup. So I test connection etc again to get the same result. Then I try to sign into one of my other accounts and they all work just fine. However I'd really like to have this account as it has the most work into it.
