GUI stuck "Loading Available Products"

When I start Arm Developer Studio the GUI shows "No Product is Selected" and "Loading available products" while the busy indicator is active.  During this time the ARM DS Gold edition checkbox is displayed but it is greyed out, and the "loading available products" continues to search.  I've waited more than 30 minutes.  What is needed in order for the GUI to find the ARM DS?

Note that my ARMLMD_LICENSE_FILE is properly set.  A team member at a different location is able to run ARM DS using my license file settings.  Could this be a firewall issue at my location?
