When I load up a car/track, whether I leave it sitting on the live timing screen or jump directly in the car to drive, the game completely locks up after 15-20 seconds of being at the track. The ambient sounds such as the loudspeaker still play and I can still move my mouse but I have to Ctrl-Alt-Delete out of the game. Happens on both 32 and 64 bit. I've deleted all of my plugins.
