I downloaded a few multiplayer scenarios off of armaholic and moved the .pbo into Program Files (x86)/Steam/SteamApps/Common/Arma 3/MPMissions yet they don't show up in Arma. They don't show up in the scenario section nor when I try host a new server (all I see are the 2 missions that come with the game) I'm on Windows 7 if that means anything.
Any help? I've looked around and can't find a definitive answer.
