Simply put, I cannot get into a server that all my friends can join, and indeed my friend is the one hosting it.
I get in, download the map fine, choose who I want to be (Medic, riflemen etc) then click, then it loads a bit, says I've connected to everyone else, then it just hangs on the screen wherein the map is shown. Just nothing happens, waited over ten minutes.
Unable to Alt+Tab out, only way is to CAD it, which then immediately crashes the program without my even forcing it closed.
Rather annoying!
