Invalid Cd Key

i have just bought the game and am trying to input my key as to unlock online
i bought it of the website not steam and every character is going in
i have even tried with no firewall and nothign in the previous threads are helping me

Hi, the error about invalid keys is most likely really saying that the game cannot connect to the server to log in. You may have a firewall blocking the program, or also a proxy may be setup in internet explorer which is blocking it. Check those,
