i couldnt find anything on the wiki

Hit CTRL-ALT-DEL, open task manager and kill vtserver.exe. Restart the game. Does that fix it? You should be run the game fine.

I haven't seen this issue before from a player, but I have a couple of ideas as to how this could happen:
The game works by booting a client then by booting a server then only letting the player join it. (Turf 2 will have the game server embedded in the client to avoid issues like these).
- Cancel was pressed while starting a game, somehow messing with the connection (sometimes its okay to press, sometimes it isn;t). This is why I've greyed out the button. Maybe I need to remove it outright.
- vtclient crashed or was shut down between starting the server and connecting it.

thank you so much, i can now start a game.
