So I just bought this game on Steam, and I followed the steps, port forwarded 4321, tried UDP, etc etc... All of them!
Still getting the error of no connection tcp/ip or something.
I have read all the answers, and the forums, and port 80 is blocked from my ISP.
Nothing works! I am using Windows 8, and when i try to play online, it also asks to install something, and when I try, it says it won't because of Windows 8. I don't think that's the problem since it's trying to install Windows 3.5 Framework or something, which I have all the necessary software updated. Please help!
