Hammer, it could actually be an error on the website. Does the site work for anyone else? If you want to post a url to a page that is giving you an error I can check it out.
You may also want to lower your security settings, if you go to Tools - Internet Options and choose the Security Tab. First try clicking on the Deault Level button to reset them to the defaults and see if it works. If it still fails, go back and choose Custom Level and do a Reset to Low. If that works, try Medium - Low then Medium, etc until you find the highest level that works. If it still fails on low go back and reset them to the default level.
