Google Alert RSS feed not showing

The issue I’m seeing is that the google alert RSS feed is no longer showing any content. But when I visit the url that the iframe in the lightbox tries to display, it’s there. There may be something wrong with the redirect from the google address to the XML supplied “real url”. My client is flipping out, so any help would be greatly appreciated.

Thanks in advance.
