Published engage freezing

I have added a few engages to my current elearning.  When I preview it through the Articulate tab, the engages seem to work just fine.  When I publish the elearning and use the engage, it does not open, it just freezes and will not let you go to the previous screen and will not allow you to click next because you have not gone through all of the content.

I am using the same engage twice in the elearning and it will work for one path but not the other.

Any thoughts?

Thanks!
