The procedure to update to this firmware is a little different.
Steps are the same thru running HIDBootLoader.exe, then

1)
     - Check the "Allow Configuration Word Programming"
     - Click the "Open Hex File" button and select the .hex file
     - Click the "Program/Verify" button
     - After running, will say "failure" in the dialog box

2)
     - Uncheck the "Allow Configuration Word Programming"
     - Click the "Open Hex File" button and select the .hex file
     - Click the "Verify" button

3)
     - After running, should now say "success" in the dialog box
