Class page authorization.

I was getting a bad session or cookie error.  The page output text showed that the page was the would you like to sign up for this class page, as if i did not login.  After looking through the requests made in chrome it seems that they changed how you enter a specific class page.  They now do not use some of the email and class name fields.  This seems to work on my system. 

Cheers.

Thanks for making this, I cant wait to download the videos and watch them on work trips and such.
