USN76 Ronald Reagan Carrier Help Please

I downloaded the CVN76.zip, here, and installed it in FSX Acceleration. I cannot get the autopilot to steer the ship or get the horn to sound with the "G" key. The sound.cfg looks OK and the horn.wav plays in my Audio program OK. I can steer the ship with the joystick. I even tried putting the throttle on one engine low and it still won't turn. Has anyone downloaded, and installed it, and got the horn to sound or the A/P working? Thanks, Bob.
