My kids saw it on my playlist the other day and they decided they wanted to play the game. No problem, so I re-downloaded the game and played for a few moments. I then handed the controller off to my 12 year old son and he signed my gamertag out and he signed in with his own offline gamertag. The game shut him down immediately and he couldn't play. I then signed myself back in and started the game up again and played for a few moments with no problem. I signed in his gamertag and once again the game shut down. WTF???
Xbox.com forum help is useless and the phone jail version is pitiful at best.
Any help would be welcome - thank you.
