"Unable to locate an Aurora"/firmware update

Hello.  I have an Aurora 16, via PCIe into a Mac (OSX 10.9.4).  I haven't updated my firmware in awhile (version 24), and before I install the new lynx Thunderbolt card thought I'd do so.  When I started the firmware update, I got the message "Unable to locate an Aurora" .  I was able to update the lynx mixer to version 1.0 build 56A.  My AES16e is firmware 13.1.,my Aurora's firmware version is version 24.  I tried unplugging the power cord to the Aurora and holding the trim button to "reset" things, but that hasn't made a difference so far.  When i try to open the lynx remote control panel in the dock I also get the "Unable to locate an Aurora" message.

tonight i was able to get a different MIDI interface (Native Inst's Maschine Studio) to help me connect the Aurora via midi in and out.  Now the midi light on the front of the Aurora is full lit green (I assume thats good).  i have all other cables disconnected, so only midi is connected at this point.  The ARC now boots up on my Mac Book pro, showing it is connected to the Aurora with the current firmware rev 24. .  however when i go to install the new firmware update (v28), i still get "unable to locate an aurora"?   ...i'm so close, what am i doing wrong??
