Coursepress Sign up button just hangs

I really need assistance with this. I first mentioned this nearly a month ago - that coursepress just hangs when a user attempts to enroll in a course. You guys acknowledged this as a known issue but I've seen no update since.

Here's an example of a specific page where we are having a problem : http://goo.gl/MXPniE

I've tried turning plugins off to identify the issue but it persisted. Can I please have some assistance with this?
