Ok, so I downloaded MM3 before and it worked. THEN my game started acting up. I uninstalled the game. I put my maps where they need to go. I put MM3 where that needs to go. But, NOPE. MM3 isn't showing up in my game. I dunno what to do. I extract all > copy > paste in textures > replace and copy > nothing. I don't know what to do. /:
