Greg747.zip Autoland

A couple of weeks ago I downloaded the above panel by Mackem Greg from Avsim. One of its features is an autoland system. Tried it out last night, but I couldn't get the autoland to work - OK until 50 feet from the ground, then either the plane goes nose up, stalls and crashes, or it goes nose down and crashes into the runway. Has anyone been able to get it working properly? If so, can you tell me what I am doing wrong. All of the pre-conditions are there, I have throttle to zero and I have tried reducing fuel. I have a FF2 joystick (although obviously I am not using it) - don't know whether this is having an effect.Thanks for any help.Boogie.
