HTML5 on webserver, stops loading/freezes

I have several projects that I published in html5 and have uploaded to my web server. When I view the projects via the link, they freeze when trying to navigate through the slides. I am using iSpring Presenter. I have tested using Chrome, Firefox, and IE.
Has anyone else experienced this? If so, how do I fix this issue?
Here is a link to one of the projects:
