Crash to desktop ? please read here:

[Chris B.]

I've had this problem too and it was giving me a hecktic time. Very disheartening to almost finish a long hours flight only to have the thing
crash on you.
Some have mentioned to make sure that your video card drivers are up to date and that's a good idea to put to effect.

What I've learned to prevent the problem from happening is to curb back your audio acelleration. You can do this from either the "Sounds"
category on your control panel. Or if you go to Start>Run and type in DXDIAG. This should bring up a screen for the Direct X diagnostics
screen. Go to the sound tab and look at your accelleration setting. It's probably all the way up. For me I set it back one notch and that fixed
the problem.

Another thing about the problem I was having. When flying to a non-tower control airport the program works fine. It was only with the tower
radio supported towers that it would crash after tower hands you off to ground following a landing (hopefully this is the same for you).

So just give a check to your accelleration setting.
