Authentication error XBOX account When i try to log into bungie.net woith my xbox account is says: Authentication Error We were unable to sign you in with your Xbox Live account. Please visit xbox.com and sign in to verify/update your Xbox Live account. This error usually indicates that your Microsoft account has no Xbox Live Gamertag, or that your account must be updated in some way, such as agreeing to an updated terms of use. I have called xbox support and they say its not a problem from their side, that i should contact bungie for help.
