Flickr Search Connectr for Windows 7...Cool if it Worked

"What is this? A new feature of Windows 7 is "Search Federation" - the ability to search remote document repositories such as Flickr through the native Windows search interface. This is a custom Windows 7 "Search Connector" which can be installed to communicate to the Flickr OpenSearch translator implemented on this site."

I was reading the one and only computer magazine that I subscribe to this morning - Maximum PC - and they mentioned this tip for Windows 7 that would allow you to directly search Flickr for images from within Windows Explorer. It seemed like a neat idea, and a quick Google search brought me to the site that has created the tool for making this possible. I installed the tool, and typed in my first query - dogs - and waited. The result? An error message stating "The location cannot be searched because it no longer exists or is temporarily unavailable." Well that's no fun! I cracked open the connector bits in notepad, found the search URL that was being used, and tested it with a hard-cored search string. It worked. So I'm a bit baffled as to why this won't work for me. Anyone else have better luck with this than me?
