People are asked to help with one problem. When you start the game gives an error message that says: unable to connect to server. Yes, after clicking the next button, the game immediately throws to the website with the support, where is the key answer, but when I enter this key, then the button which is responsible for the completion of this procedure, and then running the game does not become active. If who faced with this problem, please help.
