Here's what's wrong.. WAIT WAIT, do try the login button, like Missy124 said... I didn't try that.
But I had the same problem with the login page until I downloaded the new launcher. (Link thanks to Augie Doodle.) They made a new install launcher like two days ago that messed a lot of stuff up... You can download it here.
