Firmware Update failure ex 6200

[Stnigro43]

I tried to update firmware for ext 6200.  Had to bypass Genie.  After downloading the correct update I tried to select it from my desktop as directed and it simply fails to update.  When searching for update by ignoting the downloaded file it simply spins on and on without success.  How do I successfully update the firmware without killing the extender?

Thank you.

What exactly does the label on the EX6200 show? EX6200 or EX6200v2? EX6200-100xxx or EX6200-200xxx? What is the current firmware version in place?
