I bought the NBA2K14 Super Fan Pack. I downloaded and installed the game using my XBox account. My son wants to play and start a MyCareer mode using his XBox account. If he's the only one logged into the XBoxOne, he cannot launch the game. I asks if he's purchased it and takes him to the XBox Store. So, I log in using the 2nd controller with my account. He can now launch the game, but, when he goes into MyCareer, it's under my XBox account and he's unable to switch to his XBox account. Is there a way for him to play this game using his account properly?
