My ART SSC has a firmware v1.14. I want to upgrade it, presumably using eManager. After installing eManager, it properly lists my device at the correct IP address, indicates that it is "Ready", but lists no other specs for the device in the right-hand panel. When I try to perform any task, specifically 'Upgrade', it says 'Preparing' but sits there forever with no progress. What could be causing this software to not communicate properly with my device? I also installed ArtMan, which connects just fine, and will display all of the pertinent information. It, however, doesn't have any newer firmware available for upgrade. It will, coincidentally, re-install the existing firmware successfully. Any advice is greatly appreciated.
