Heeeeeeeeeeeeeeeeeeeelp! I have errors and blank pages related to coursepress

I have blank pages and pages returning 404 errors and need it fixed asap! I have already enabled support access to my site waiting for someone to help with the blank pages. Now my courses are returning 404 errors on the Units page.

For example, on my Twitter course, as soon as I enroll and click the button to start learning, I get the 404 error. By the way, the Start Learning button returns a 404 error no matter what the course is.

The STUDENT Dashboard page that is supposed to show the courses the student has enrolled in is BLANK. I have had another ticket open on this since Sunday with no resolution so I am including it here again.

I really REALLY need these two issues fixed right away.

Can someone PLEASE help me fix both of these issues??? Please
