NFS Underground freezing

I’m having a problem with this game freezing on my 360. As soon as I enter a race, the game freezes within 60 seconds. Has anyone else had this problem?

It’s probably doing you a favor.

I put several hours into the game. In fact, I finished it. But I never had a problem with lock-ups on it. Any chance you can try some different events, or is it every race?

Every race. Tried several different ones. I don’t see any scratches or defects on the disc either. Never had this happen before.
