Oh, sorry, I skipped one. It really goes:
Computer/OS (C: )/Games/Beyond the Sword/Mods/Rhye's and Fall of Civilization Europe/Private Maps/RFCEurope
Yeah, cause the last one isn't a folder, it's the worldbuilder save. My bad!
But at the beginning, I did have a double folder. I had put it into a new folder I made, then there was another folder (compressed) named RFC Europe, then there was another folder inside the compressed one called RFC Europe. But I fixed that; before I fixed it, when I loaded the mod, it was EXACTLY the same as the normal title screen, except with the option "Unload Mod" at the bottom of the menu. After I fixed it, I got the title screen labeled "Rhye's and Fall of Civilization: Europe", and I got the music, but everything is still the same; I can only access the normal maps.
Usually how I access mod maps is by loading them from the "Beyond the Sword Content" section. I think my problem is how to load the map, because I can't find it, and when I try to load it directly from the folder, I get a bunch of error messages.
