Just picked up R6 since it was on sale, and am bummed to find it not working. I'm running Win 8
and when I try to boot up R6 I just get a black screen and a cursor. If I click or hit any keys on my keyboard the whole thing crashes to desktop due to "fatal error".

I tried the DXWnd fix that some people are talking about on these forums but it didn't help the problem at all. Contents of sherman file follows:

ACTIONKEYMAPPING: Could not open mapping file sherman.kmp
OPTIONS: Could not read key mappings from sherman.kmp, using defaults
Renderer::Fullscreen() failed during CreateZBuffer() in file C:\Develop\Common\Renderer\renderer.cpp at line 1002
Error = "Action not supported."
We are sorry, but we are unable to initialize the renderer at 640x480x16
SetDisplayMode to 640x480x16 failed.
