Thanks for sticking through this. I've updated the program to remove the dependency on the VC runtime DLLs. Hopefully that should fix your problem. If not, I'm out of ideas as to what could be wrong. I also fixed the shaders so that they should compile for people with non-nVidia cards.
That made it work, and I must say it's an impressive tool for navigating maps. Now I'll just have to make due with my single core cpu, Radeon 9800, and 2gb of RAM blazing away at 3.0 to 8.0 fps. Thanks again.
