Crashing Issues

Got game crash in a mission.
When you have to take the special cargo from Oxnard to Lebec to receive further instruction on the delivery's destination.
After dakota has stopped the truck chasing you, you receive informations to continue to the truck stop ahead.
There should be a video cutscene at the crossroad to Los Angeles however the game crash everytime there.

(Please USA Trucker, don't say it comes from CPU config. I played the game for more than 40 hours without a crash.)
