Hello all. I just received AFPD as an early Christmas gift. I'm very pleased with it, however, it's been crashing when I switch sceneries. I have the very latest version of everything, including DirectX and AFPD. I'm updating my video drivers right now, however, I had the driver version before this one. When I exit to the main menu, I can select another aircraft, then another scenery. When I click fly, it does the lovely error reporting bit. It's a "clean" crash, no BSOD's or hardware problems.

Specs:

3.0 ghz P4 w/ HT
1 gb Kingston Value RAM
GeForce 6600GT w/ 128 mb ram
ASUS P4P800SE mobo
1x 200 GB 7200 RPM HD

Any suggestions?
