I'm also having no luck with the upgrade. On Win 8.1 64-bit. It always displays -16.-16 as the version, even after restarting the GUI.
When trying to upgrade the firmware it says
Your firmware version is: -16.-16
The latest firmware version is: 2.2
And then locks up the GUI when trying to upgrade.
Here's some flirc_util.exe output that replicates the commands above. I'm new to all this so let me know if you need anything else, and thanks for any help!
