That is weird, because I tried going to their webpage using the link you pasted above in both Mozilla Firefox and Internet Explorer, and no luck. Is it possible that you've visited the Radian webpage before, and your browser is just using a cached copy? Sorry, I'm a computer geek (it's what pays the bills). In other words, if you've visited the Radian webpage before, it's very possible that your browser (probably Internet Explorer) is just accessing the cached, or saved, version of the webpage that is stored on your computer. I have my browsers set not to cache, so each time I access a webpage, my browser acts like I've never been there before.
