Feral Heart

So I made an account when the registration was open and activated it, but when I go on the game it says my account is invalid? I tried everything from resetting my password to redownloading and nothing worked! I can't make a new account because registration is always closed and that's the only other thing the people have told me to do and it's really ticking me off.

Can someone please help me, because if not I'm not playing this game and will spread how buggy and unreliable it is :/ I shouldn't have to go through all of this to play a silly rp game.
