Custom registration form for Coursepress

We have coursepress installed along with the coursepress theme here:
course.changeyourlifewiththelaws.com. We need to add a couple custom fields to the registration page and be able to have those pieces of information show up on the course dashboard page after logging in. Is there a plugin or setting known that makes this possible?

There are a lot of plugins for customizing the registration page, but I'm not clear if Coursepress uses wordpress default reg page or not. I also installed RegistrationMagic-Custom Registration Forms 2.5 to customize the registration page, and it broke the entire site. So I have that plugin removed now.

It seems simple enough that I should be able to figure out a way to make this happen. Any insight into achieving this is much appreciated!
