Guys, forget about playing this game online without having an original copy. If you buy the game you can create
ONE valid account to play online (One account per valid CD-KEY), is not the same thing as it was with Battlefield 2 anymore. After you have an account you can play anywhere, maybe with a non valid cd key too and a mini-image but im not sure. The only solution if you don't have an account is to use the crack from razor to play single player, lan or online via Hamachi. The crack from razor just avoid the game to get to the internet to check the account, so once the game thinks that there is no Internet available, it lets you play single or lan mode. Of course all this with the pre-created profile from the razor release of the game.
And sorry for my english
