Feral Heart

I recently downloaded Feral heart again and i tried logging on to my old account and it worked but when i tried to join the game it said "can't connect to front server" even though i was logged on, on the "Play game" site that needs to be open. So i made a new account because someone said that might work but i still had the same problem. I've tried redownloading and deleting everything, and more. Please help, i don't know how to fix this.
