[JiggaJigga]

Hey guys,
I downloaded the Command and conquer 3 demo not too long ago and after about 20 mins of playing it automatically crashes to desktop. Would anyone know the problem and if i bought the whole game would this problem happen also?

Thanks for any imformation u have on this problem.
