I've got two issues going on with my ST Pro. First, after about two balls played, auto fire kicks in and launches the ball after each drain. If I turn of the machine and start over, I can get about two balls played before the problem starts again. Second, I am not able to change missions with the flipper buttons when the ball is in the launch lane. If it's locked in the left mission start I am able to scroll through. Any thoughts on trouble shooting would be appreciated. Thanks in advance.

Thank you. I tried both and still not having luck. It works for a game and then goes bad again. And the ability to scroll through missions never comes back, even in left lock now.
