and i have been playing this game and the other 2 since they first came out.Have never understood why it never uses the Mod folder. All mods of the game as long as the game has been around have used this method to employ mods in the game. this is where all the mods will reside and the game will start using this file. Next you need to create a Folder called Data and install that to you Directory. then on the second line change the false to true then go to file open and save other wise the game won't see any mod and will play in vanilla mode.
