Thanks, Paul. The firmware update to 2.04.72 worked fine.
One other thing that might help too.. On this page where it refers to "EFILive Control Panel" it might be worth mentioning that is part of the V8 software.
That explains why I couldn't find the "F6: Firmware option in the left-hand pane" -- because I was looking all over the V7.5 app for it.
