Serge,
Thanks for the modified files! I was thinking, "Why does this work for everybody else, and not for me"? So, I took another look at when FSX crashes and noticed that it was when it was loading all the "eye candy" graphics. I reviewed the graphics configuration in FSX settings and found that most of my sliders were at their maximum values. So, I reduced a couple of sliders, and was able to run the KNAR scenery at night, while in free flight mode. Mission three still crashes, but I think that if I reduced a few more sliders, I might get the missions to run. I'll let you know.
