I just got my brand new laptop yesterday, and I downloaded Civ IV onto it. It worked perfectly until this morning when I downloaded the 1.74 patch. Now the game won't start--it just gives me a blank black screen with my cursor in the middle.
Oh, and by the way, I run on Windows 7. Can someone help me?
EDIT: I fixed the problem, but now I have an error that says "Error loading shader libraries".
