Hi there, I want to play cod4 multiplayer on LAN server but when I go to start a new server and sets the option to Dedicated: LAN after start the game it crashes without giving any error when I restart it only error gives ie. The game is already running. whenever I start the game with Dedicated: No then no problem occurs. Anyone know this weird problem and have a solution for it?
