Downloaded it and ran it out of the box, and got a "Not Supported" error, "web browser is not supported". Using IE 11. Looks like top.js is looking at navigator.appName variable to determine if it's an IE browser, which now is set to "Netscape" in IE 11, and user agent is "rv 11", no longer "MSIE".

Could it be you're running IE in compatibility mode?
