Ric,
I've never seen this error before, so I'll need some more information. When does this happen? Can you leave me a private message with some more of the logfile? And can you check the /var/log/binlserver.log as well? Is the binlserver telling the client to download this file? If so, then you may have imported a binary .inf file. The .inf file you import should be human readable. Check that first, if you can't read it with notepad/vi then you need to download another (specific RIS-)driver for your network card.
