i cant play halo because it says im not the subscription holder. i just renewed my account a month ago and i try and play it today and its says this crap? WTF!!!
Verify your subscription status at account.live.com. Also, are you able to play multiplayer on other games, or is Halo the only game not registering your Gold subscription?
If Halo is the only game showing issues, hard reset/power cycle your Xbox and see if that helps.
