I've been trying for the last couple hours to install this mod, but I just can't get it to work. I unzip the file and drop the gamedata folder into Kerbal Space Program's gamedata folder. But when I load up KSP, the hitchhiker, cupola, and mobile lab are gone, and no new parts are added. I even got rid of all my other mods and it still didn't work. The mod also comes with a slightly older version of module manager, could that be the issue? Any suggestions are greatly appreciated as this mod looks absolutely amazing.
