Oops. I guess I transposed a couple of the numbers. I installed the version that was out on the support page, 1.2.1.
The upgrade was easy to do.
1. Download the zip file to the computer
2. Plug in the NOOK
3. Drag the zip file to the "NOOK" drive
4. Unmount the NOOK and unplug it.
5. Wait for a few minutes.
The technology is pretty easy to use. Finding out what needed to be done was difficult.
