Are there any news on this topic. I got the same problem and also contacted the support. The only thing they could tell me was to reinstall Windows and FSX again so that it would work. But my system is stable, I got multiple addons installed and tweaked my machine. So it would be a process of weeks to get the actual state of my flightsim. Is there no other way? What's wrong with that plane?
