Import/Export For Coursepress does not work

I was so excited to see the Import / Export in my update of CoursePress Pro. I had manually moved 3 out of 12 courses from an old to new build, which was a good hour task per course. I immediately put down what I was doing and opened up the old site, did the upgrade, and exported the remaining courses. Then - came to the new site and did my import.
Nothing.
Not one course imported.
What a let down.
