ok so when i first bought killing floor it was on my laptop and i realized it was too laggy so i downloaded on this computer. For the first two games i played on this computer it worked perfectly, but then i logged out of the game and came back in the game. Thats when i couldnt see any of the names of the servers or anything.I went back onto my laptop and it was working perfectly (except for the lag). I tried restarting it, redownloading it, opening the port and still nothing. Any help?
