I have heard and read through the help section on BO2 and it says that I have to "Double-Click on a friend's name" But when I do that it says "joining game session" and then never actually joins the person. I have tried loading into a game and starting it and then have my friends join but they just get stuck on "joining game session".
(I have my in-game party privacy on open BTW if that helps.)
Any ideas of what might be wrong?
