Hi 2byts, that's a bummer I thought that was going to be the culprit.

Are you running any other software that might hook itself into running programs at a low level like anti-virus/anti-malware type stuff?

Did you check if there was a newer video driver available?

About the last thing I can think to try is if you send me an e-mail (moi@moi3d.com), I can send you a version that has a Direct3D9 renderer enabled. One of the differences between MoI v3 and v4 is that MoI v3 used Direct3D9 while MoI v4 uses Direct3D11. I have a version of v4 that I can send to you that can use Direct3D9 instead if the drivers for that are more stable on your system for some reason.
