I saw other questions related to this but no real solutions.  Since January 2018 I’ve been creating Captivate 2017 Responsive courses with video simulations captured first as CPVC files and then inserted into the bigger Captivate course.  Up through April, I had no problem with the slides loading or playing at HTML 5 on my desktop.  Suddenly in June this stopped working on a new project I created. Then I realized all of my old projects no longer work.

What could have changed to cause this problem?

Any ideas are welcome.

Again, it worked before…not it doesn’t work.

Thanks
