I am not sure what it is, but if it's anything to do with IE, you should use firefox anyway, much faster and a more secure web browser. you can download the traditional chinese version at this link
you could try to update java if that's the problem as well
It's likely that you might have java disabled in IE. You could go into IE option, under security, see if you have java disabled, go through the list in there. If that's the problem it should run if you use firefox.
