Extreme Off Road Racing

The car isn't even going forward, Am I doing something wrong? Is the accelerator working?

I've tried several times to play this, but I've got a weird problem every time I try. Other players have reported the same problem (or something similar, at least).
When I press , the engine revs up, but the buggy doesn't move forward!

Placed 1st a few times showing up at 10th place and im a beginner.
