I must be missing something.  I can download and unstuff the file.  I can open the VNC viewer.  And then nothing.  There is a "host" box on the VNC window, but I can't input the ip address, either manually or by pasting.  I've tried putting the ip into a browser window instead, but it won't connect to that server.
I've uninstalled the viewer and reinstalled it a couple of times.  Thanks.
Peace
