Hello,
I bought a boxed version of your PMDG MD-11 and I have a little problem with it.
I'm using Windows 8.1, so I already know that there are problems with disconnecting joysticks.
But I was able to fix this bugs with a tool, so now:
When I start a flight with the MD-11, after some seconds/minutes I can't control the throttle any more. This problem only appears with the MD-11 and only with the throttle, I'm still able to use the elevator or aileron.
I hope for a helpful answer.
Regards from Germany
