What error are you getting when you try the EK website? If it is something like 'you need internet explorer 6 to view this web page' you can download Chris Pederick's User agent switcher which 'tricks' websites into thinking that you are using Internet Explorer when you are not. It often works without flaws but sometimes not all aspects of a website may work. Even if this doesn't solve your EK Problem it's a damn good addon which might solve future problems. Suck it and see
