For some reason I am not able to play any games. I have Call of Duty Ghosts (Digital download), killer instinct, and the Kinect Sports Rivals demo. All these games were downloaded so I don't need any game disk to launch the game. But when I select the game to start playing, it goes to the initial load screen with the title name but just after a few seconds it kicks me back to the home screen. Netflix loads, the tv app works, I just can't get it to launch the games. This happened earlier today as well and eventually my controller was sync'd but wouldn't do anything. I unplugged the console for a couple minutes to make sure the system fully restarted and everything worked again, but after watching a couple hours of tv, now the games won't launch again. Anybody have any idea what's going on?
