FSX-SE Elevators and Ailerons Messing Up

In FSX-SE, when flying a mission (probably in Free Flight too, don't know how to really test it since it happens part way through the flight, and I usually don't do my flying in FSX (I use P3D for that)) the elevators and ailerons will mess up. Part way through the flight (it worked fine for the start of the flight) the full 100% movement of my Saitek yoke is only maybe 5-10% moment of the aircraft's elevators/ailerons in the sim. (the sim aircraft's yoke moves the whole way in the VC, but the elevators and the plane won't move the whole way.) I think it happens in all aircraft but I know the default F-18 and 747 for sure. The missions that I know it happens in is the 747 Test Flight mission and the rocket launch guard mission.

Does anyone have any ideas as to why this is happening and how to fix it?

Thanks very much. This is very mysterious to me.

Sounds like the AP is being activated. Try hitting Z, and listen for the AP cancellation sound. Usually a series of beeps of some sort.

Or it could be a mission commanded hydraulic system failure. If it's that, all you can do is declare an emergency and find someplace to land.

Let us know what happens:)

No AP is on. It happens on two different missions, and the same missions work fine in FSX boxed, so I don't think it is a mission command.

Thanks.

It has been fixed. I needed to change the Co-Existence value in the Registry Editor so that the FSX-SE directory in AppData\Roaming could be created. See here: https://www.avsim.com/forums/topic/533655-fsx-se-elevator-not-moving-whole-way/?do=findComment&comment=3829125

Thanks.
