  1. This was exactly what I needed however when i run it it gets to yahooHTTP.send and come up with an error saying that a connection could not be made to the server. Any ideas?

    1. Hi Ryan, I just tried connecting and its working for me. I had the connection problem using company network too, probably because the router is blocking the connection.

    2. Are you trying with your personal computer at home, or are you trying with your computer at company?

  2. Hi Wyman, Just tried again with no success. There must be something in the work network blocking the access. Do you know if it uses any particular ports? Do you know of any other ways of achieving the same result of downloading the rates?
