Don't worry about it. Simple misunderstanding.
I have tried it in IE 8 and IE7 on my wife's machine. It works.
Have you got Java installed? I can see on the source it has quite a bit there.
But, as suggested, you could try another browser, only to see if you have a wrong, or incompatible, option set up in IE
For starters - have you tried it in Compatibility mode (IE)?
