I didn't make it!
I just downloaded the Civ 4 patches 1.61 and 1.74, and now everytime I try to play it gives the error
"C:/Program Files/Firaxis Games/Sid Meier's Civilization 4/python24.dll is either not designed to run on windows or it contains an error. Try installing the program again using the original installation media or contact your system administrator or the software vendor for support."
I really don't want to install the original Civ 4 back, because then I can't play online :(
