I did a search on the forums using my own account. Looks like a few other people have had this problem, and reinstallation has fixed it in a few cases. Try reinstalling, and let me know how that goes.
Also, I successfully registered a new account on the forums. You don't login on the front page, you login to

I just reinstalled it and the same thing happened, but thanks for letting me know about the Gametoast thing
if you find anything else let me know.
