Feral Heart

I don't have a password with numbers though, so that can't possibly be the issue. Also, I tried creating another account(brightlypaintedblack), just to see if that would work, and the same thing happens with it. Neither work, and both have passwords with no numbers.
Is this possibly something that will pass? I know earlier, when I first found the game I couldn't register, but I waited a day and then it did. So should I just wait til tomorrow and if its still not working ask for more help?
