are you trying to use the IP the game tells you to use? (don't tell me the IP)
Yeah the one that you have to click on to show
Don't use that one.
you should type in the start menu, "cmd" without quotes, then you need select the first result, lastly you need to type in the box that comes up "ipconfig" without quotes. Your local IP should be to the right of "IPv4 Address." for example "192.168.254.57"
