Doesn't work for that site. Archive/Whatever only works if a site lets Google have free access so Google can index it and that one (like most off-brand news blogs) doesn't.
That's not how Archive works - it saves pages using people's browsers. Try archiving a page yourself and you can watch it do so.
What it shows you is a progress report of what it is doing on the server. If you queue something for it to archive and close your browser and then come back later the page will be archived.
