Thanks for the tip.  I  did that and get this:

Firefox can't establish a connection to the server at 127.0.0.1:7776.

    The site could be temporarily unavailable or too busy. Try again in a few moments.
    If you are unable to load any pages, check your computer's network connection.
    If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.


I have tried on different browsers but with the same result.  I guess I will have to skip the world of NHZ for now.     Oh well.  Thanks for trying.
