Virtual Key Instant Win (Issue w/ redeeming code)

I won a Driver Gear code from Xbox Live Rewards. I try to redeem the code, but get an error message. Has anyone else run into this problem? The error I get is:

"Sorry, an unexpected error has occurred. The error has been recorded and we will investigate. Please try to redeem your code later.


You probably have to wait until the actual game is released not just the demo.
