I checked the official website of FeralHeart and although it appears that it's working and users are playing, I can't create an account. The setup package was downloaded successfully, but there is no way to log into the game. Therefore, make sure that your account is valid (you can check this using the login form, just log in and access your account). Secondly, start the game and make sure that it's allowed to connect to the Internet. Use the simplest settings to allow an app or game to connect to the Internet in the Firewall window.
