Am I the only person that CoursePress Pro doesn't work for???

I cannot add any content or modules to units. I have tried logging in from different browsers, different computers, and clearing cache. My course goes live in about 24-hours and this is my livelihood on the line. I see in the community that another person has had troubles ongoing as well (but different). Am I right to assume that this plugin works well for everyone else? Is there anyone out there who it’s working well for that could comment? I started this thread days ago but apparently it’s of no interest:

I thought I’d just use Protected Content as an end around but when I activate it, I get error messages all over my site.

Is there any hope or do I have to trash this plugin?????
