Terry,
are you getting a failure message when trying to open GE in Hummviewer?
I had that problem when I started to work with Hummviewer. The problem was that I had to tell Hummviewer where to look for the right file to open GE.
I cannot remember how I corrected this setting, but I'm sure you're facing the same problem here.
Try to find something in the Hummviewer subforum. Martin wrote a post about it there as far as I remember.
Good luck and regards from Germany
Harry
EDIT:
Here is Martin's post I was looking for:
