Wireless Keyboard Firmware update fail - a key may repeat unexpectedly while typing.

I followed this article: http://support.apple.com/kb/HT4010 downloading the firmware, quitting all apps and after following the directions I receive the error message saying "No aluminum keyboards were found" and yet my Bluetooth indicator shows the keyboard connected.

My keys go in and out of repeating unexpectedly and yet the update can't even read the wireless though it's connected. Anyone have a solution?

kindly, Matt
