It same there - see attached screenshot. It seems that for some reason your browser cannot read the gzipp-ed content that is coming from the CDN server. There was such problem in previous versions of the browser, but you should not experience it in IE9. This leads me to believe that the problem might be related to some proxy that you use, that truncates the type of the content in the header so the browser cannot properly read the content. Could you please verify that? What happens if you open the site from another network (again with IE9)?
All the best,
