I was having the problem where the XML was being generated, but there was a path issue:

Now, I see the flash is loaded, but the gallery will not display. I thought it was a firewall issue, but I've tried the site from three locations now.

I've gone over all of the steps several times, but still cannot make it work.
Any ideas?
