Problem solved, i have got to run the server but now i have a Little problem, it's a bit strange, in console, where it says Gamestate, when first you get offline, and after validating the server with the server launcher you get IN_GAME i get POST_GAME instead, and when i want to change the map, no matter what it is, it changes the map, but when i enter the game for myself for playing it loads up the alborz mountains only, do you know what is this all about?
