Coursepress registration is NOT WORKING AT ALL!

I created a test class because I'm having SO much trouble trying to make this work.

1. I once was able to create a user account. Now, when I try to go back to access the class, and click the "already have an account?" link... it sends me back to the details page.

2. I tried to create a new account and sign up for the class from scratch... I can't get past the "Review Your Cart" page.

3. I paid several hundred dollars for the promise of 24/7 support... the Live Support that's supposed to be active right now is CLOSED!! Live support through a chat room is AMAZINGLY INEFFICIENT. I wait hours, sometimes DAYS to get any sort of response.

I run a business! If this can't deliver what's been promised, I WANT MY MONEY BACK!!!
