I downloaded the game a few weeks ago. And I did successfully played it once.
However, yesterday when I tried to launch the game, it freezes at the first loading screen (title screen? I don't know).
It is the very first screen showing "Kinect Sports Rivals Preseason" after you choose to launch the game from dashboard.
At the bottom right corner there were some squares blinking which I presumed means loading. But it just kept "loading" for at least 15 minutes.
I tried to reboot the console and launch the game again. Same.
Then I launched other games: Dead Rising 3 and Killer Instinct. No problem there. Only Kinect Sports can't launch.
