It's not working for me. If I click the start button it says "your pass phrase is less than 35 characters long and is not secure" or something like that. On the second click it says "you must enter your pass phrase".
I've removed any notifications and error messages associated with password length, but any sort of not allowing you to log in should only occur on the mainnet.
Could you try hitting ctrl + f5 (if your on windows) to do a full refresh of the page. It should work after that.
