Well I love Left 4 Dead 2. A lot. And recently I've been having a problem with its connection. I'll get online and it will say "Versus - Dead Center - 9 lobbies" and I will click on it and it will say something along the lines of "connection failed, 8 more lobbies" and it will count down until it forces me into a public lobby that I lead. The thing is, I'll sit for 10 minutes and no one joins. I even join friends' games that have 5/8 player slots in the server and it will say "session is no longer available" and spit me out at the main menu. I've tried restarting my game, I've tried restarting Steam, I'm tried restarting my computer and it still won't let me join any game. Not even games that have already started. I can still connect to the internet, see my friends on Steam, and Counter-Strike: Source and Team Fortress 2 both work. The game will start up just fine, but I can't join any games... does anyone know what's wrong or how I can fix it?
