Rev Slider Only Displays First Slide

The site at uses revolution slider and used to cycle through five different builds. Suddenly it only displays a strange half transition right when your browser displays the site and then it just stays on the first slide. I don’t see any JS errors either.

The plugin was out of date so I updated it and am now on Wordpress 3.9.

Any idea what’s happening?

Thank you.

Your slider working fine , i have visited your site.
