Ed, Sorry, I looked at the URL in your second message www.box.com and that works. The URL in your first message to a specific shared file gives me a 404 response too.
This is a file sharing site like dropbox so it appears the file owner has removed it. I tried a few of the web page archives such as wayback machine, a series of them are at this URL http://www.searchengineshowdown.com/others/archive.shtml but www.box.com has a robots.txt file that prevents crawling when honoured so there is nothing in the history.
