problem with in game video

[cheesybobjofran 1]

The main menu's and sound and all controls and everything work. However I am not able to see anything... Not the Helo, scenery, sky, ground... anything it's just blank. However I can feel the feedback on the joystick and hear it respond so I know that is working but I am getting no video. I downloaded it from Steam and it worked for a short time and now is no longer working.

A quick fix is to press 'left shift' and 'num pad minus' together, then type 'flush' and press 'enter'. ...
