As I don't use PC for the game I cannot verify. But have you tried to create the account with something like Firefox? Then maybe try back with chrome after you created the account. We don't typically have issues running on Chrome but there is a first time for everything...
Let me know if it continues being an issue Crunch.
I had to use FireFox to make the account, but FireFox wouldn't let me actually play the world, just log onto my account, so I log onto my account now with Chrome, and Chrome now lets me play.
Basically Made the account with FireFox and played it on Chrome.
