Ok, I just installed the 4.0 mod, and the patch to follow up, but when I load BTS I still have the same old game. I don't have the extra civilzations or anything. Yes, I have 3.17 installed. I also had the mod install in the default installation location "C:\Program Files\Firaxis Games\Sid Meier's Civilization 4\Beyond the Sword\Mods" I checked the folder myself and in the "Mods" folder, there is 11 folders. Some are called, "CIV Gold", "FfH Age of Ice, and more etc.

Any idea why it won't work?

ok nvm it just takes awhile to load
