Polaris Lock Up

I’m having an issue loading the 3rd Polaris race (under Seeker cup) at Virginia Int. Raceway. The game seems fine but when you try and load the race it just continues to load infinitely without any way out or sometimes when it tries to load the race, the game kicks out to the Xbox homepage. Any body else getting this or any ideas on how to fix? The only thing I can think of is uninstalling the game, then trying to re-install it.

I had a similar thing happen yesterday when loading the Aston Martin Vulcan Challenge
