Game crashed again around May 1862. It's done this each time now. I'm trying to find the save game on my computer, but I can't get to it. I have the logs though and will send them in.
Found the save files and sent them in.
I have a strong computer. Vista operating software, however. I had lowered the graphics option the lowest level.
Update: When it crashed it told me to e-mail tech support with info; I did that. However, I started it up and have now progressed a couple of turns in the game.
