I just recently changed my live id in Acount Settings and changed my password!
Then i started my game [Microsoft Flight] and then i tried to login and it said "The Windows Live ID is not valid or not exist". Then i started another game [GTA IV] and still can't login. I can login in this browser or any! I mean i can login in XBOX LIVE, Windows hotmail etc but can't login in game!
Please HELP ME!
I really want my account working! :(
