I'd like to add my name to the list of people who are completely unable to play multiplayer games. I downloaded PFPortChecker, used ImpulseReactorOptions to change my used ports to 7112-7132, forwarded 7100-7200 and 6073, both UDP and TCP to my comp, used PFPortChecker to check all those ports and ensure they're open. I've disabled the Windows Firewall and I am still unable to join a single multiplayer game. If I use the automatch, it most of the time flashes that it's trying to connect to a game, and then goes back to searching (Previous to the patch, it would always try to connect, then would fail to match up with everyone in the game).
If I go to custom games, 99% of them will say, "Attempt to join game failed", the other 1% just sit there on the connection screen.
I've been trying consistently over the last few days, and have spent hours on this. Considering the game has basically no singleplayer except practice for multiplayer this is sort of crippling.
