Hmmm, I'm not sure. I just went in there and everything worked fine for me. Do you have the latest version of Java installed? You can test your Java
here. If you need the latest version, you can download it
here.
Another thing is that it's possible you might have problems with Java if you don't have the latest version of your browser (Internet Explorer, Netscape, Mozilla, Firefox, etc.). So if you've installed the latest version of Java and it still doesn't work properly, try installing the latest version of your browser, if you don't already have it.
Please let us know if it's still not working after you try that stuff.
