Ok, I have received absolutely no help at all, and I have posted about this problem previously. Civ IV Colonization crashes every time I try to play a game. Civ IV BTS works like a charm, and never gives me this issue. Whenever I start a game in Colonization, I get as far as the intro screen where I receive my commission, the year is 1492, blah, blah, blah. When I start the game, it freezes for a few seconds, and then it crashes to my desktop with the usual "Windows is searching for a solution to the problem" BS. Will somebody please help me? I am getting sick of it. Edit: Ok, so I solved the basic problem by setting the graphics to Medium, but now my ships sail underwater, and a bunch of grey, angular shapes flash across the screen. Any thoughts?
