I'm not that good at downloading mods, this mod looks really fun and I would like to play it but I have no idea how to get it to work. I've already downloaded it but it won't work. I'm using winrar. Whenever I click on what I think is the link it says some stuff about how the mod won't work and it takes to regulur civ 4 beyond the sword, do I have to extract the file somewhere? And if so where?
