Xbox 360 Version Technical Support Needed

When I try to start up the PlayOnline Viewer to install the game, I get the message 'Could not start the game. Please download the game again.' I've cleared my cache, resetting my Xbox, and there's no memory on my harddrive of the game. Before this happened it started up fine, until I accidentally hit the 'Start Game' button before reinstalling the game.

COuld have corrupted something. I had this happen once and I couldn't fix it without reinstalling.
