No problem. I've only had this happen one other time--the Horizons mod for Eador. I also tried to play that one off my desktop at native rez of 2560X1440 and got the same black screen of death lockup. Played it in a window fine...

Interesting. Yeah, the game itself runs at 1024 X 768, and by default, in full screen mode. If you can get it running you can go to Windowed mode, but there's no way to do that from the outside. Let me know if you need it, and you can PM me an email address, I can modify a preference file on my end to run in Windowed mode and email that to you. Or you could try to temporarily lowering the resolution on your monitor and seeing if that helps... Though my display's running natively at 3840 X 2160 and the game still kicks into full screen mode without hesitation.
