ToCA Rave Driver problem

[RedStar]

I've installed ToCA Rave Driver and everything runs beautifully with no lag on high settings. After starting a new career, for the first 4 or 5 races it's all fine with no problems, but than after selecting to race the 5th or 6th race, the game goes into a black screen momentarily, and than just goes back to Windows.

If I run the game again, and load, I try again (selecting "race") but the same thing...black screen , Windows.

Any help is appreciated as the game looks great and I hope to be able to finish it before getting ToCA Race Driver 2.

Oh yeah, I'm running XP Professional, latest sound and graphics drivers etc.

Oh...also sometimes the cars start crashing into invisible barriers and start rolling and spinnin all over the track!?!
