Engage Interactions not working when moved to server

I began the course in PowerPoint with Engage and Quiz Maker interactions. I imported the slides and interactions. All of this was done using Dropbox.

I love Storyline and it works perfectly until I publish using LMS option to my local hard drive, View Project..... still perfect, zip file to local drive, copy zip file to Dropbox. And the engage interactions are blank.

In older posts, I see plenty of discussion but I can't find a clear solution.

Any suggestions?
