Game won't create password

I got a email verification for this game and I clicked to create a password, and it didn't work. Its really frustrating as the first time I had this error (a robot saying to check the URL again because it is not working) I just assumed I clicked on an older send of this email because the first time they sent it I didn't get it but the second time I got both. I found I was using the wrong one and switched, but got the same exact error. I would really like to play this game so any help would be much appreciated.
