Feral Heart

A few days ago I decided to download Feral Heart onto my new computer. I downloaded the game and it all went just fine. I opened the game and typed in username and password. Pressed enter, and then the message came up. I have had this problem before and usually restarting my computer helped, but not this tme. I have tried re-download Feral Heart and restarted my computer.... What may the issue be... ?
