ContextCapture deployed web viewer not working?

I chose WebGLReady format for production, and copied the resulting production folder to our webserver. When I browse to the index.html file I get the following "Please wait..." screen, but it never proceeds to the 3d scene.

Here is the actual link: http://www.wsdot.wa.gov/VERG/MP165_Rockwall/Production_1_2/App/index.html 

Any idea why this is happening?

Thanks,
Ron
