Doing a search for "Unable to create 3D scene", I found several matches, and they all appear to have to do with dx or video drivers. So it doesn't appear to be the BAIT demo that's the problem.

Regards bot placement, I'ld have 8 fixed 'bays' on the arena, and the robot / bay allocation should be made randomly, so that it doesn't matter where the obstacles or the bays are placed.
Are you suggesting that all arenas are symmetrical in nature then?
