Help. When ball one drops, game goes to reset and back to ball one again.

Thanks guys, I will check both of your ideas this weekend and let you know what I find.

Today was the first day that I have worked on my pinball machine in awhile and I still can't figure out what's causing the problem. I start a game and once the ball goes into the outhole, it starts the whole game over. Here is a video link.

Everything acts normal, the other kick out holes work the center post comes up and goes down, and the gates open.
