I'm hoping it is something simple. My Williams Grand Prix has been perfect for about a year now. My friend was playing it and went to start another game and when the game reset, it said game over! The game still requires quarters, so I first thought it just needed a quarter when he told me about it. But with credits showing in the back box, you can hit the start button, the game resets all of the score reels, and then promptly says game over. Any suggestions? Just odd that it was working perfectly, then when he went to play the next game, it failed.
