Pratically, I have installed the game, i have made a steam account, I have made any kind of registration and validation, but when I execute the multiplayer and when i click on "play", it appear a window in which is written that is not impossible contact the server or because probably the server is busy. But i'm quite sure that the server is not busy. What I can do? I repeart, the game is original and i have made correctly all the steps. I tried also to reinstall the game but it has been useless.
