F1 2010 Game crashes during driving on the track :(

[DriverN1]

I played 1st practice in China in career mode. After 30 minutes game suddenly crashed and I've got WindowsXP error message "f12010.exe ERROR"
what happened? I don't understand why my f12010 sometimes crashes... I use patch 1.01. Video driver of my asus eah4670 is updated to last version. DirectX9.0c is last version too. Please help me...
