Mark, follow up on what's appears to be going on.
When I select a converted scene (Reflex), it will work and allow me to fly. I then can go out and select another scene. But if I select an original AFPD scene, it crashes.
By the way, if it matters: Win2000, amd 2400+, 1.5gig mem, Ti4200. I don't think the PC specs are at fault. AFPD has been working flawlessly. I will keep plugging away and see if it's a specific file, if the filename is correct, etc.
Thanks for looking into it. I will be great to see it work for me.

On a side note. I also used Easyfly and downloaded a photorealistic scene made for it. However, the author of the program stated you need to start (select & load) an original Easyfly scene FIRST. Otherwise, the program would crash if you selected his modified scene.
May not be related, but who knows.
