Mouse Locks up, What's wrong?

I'm following the Breakout tutorial, and I get to the part where it says to run the game. Unfortunetly, when I run the game, the cursor locks up and the paddle doesn't move. Below are my uploaded scripts, if someone could tell me what's wrong, I'd be appriciative.

Not much code, I'd appriciate the help, I'm very new at this.
