Thx for the replys. The problem now is that I can't even start it anymore. I can open it choose airplanes, calibrate, etc...and when I press "Fly" it locks up and gives me that error message that asks if I want to send it to Microsoft. My sound accelerator is at "None". I uninstalled/reinstalled it many times and it works once or twice after a reinstall and then same problem.

P.S. Another weird thing now is that my Real Flight 2 used to work flawlessly and now all of a sudden I get errors on it as well and I can't use it.
