Updating the GP Add-on

Hi Tom, How do I update the GP Add-on? Saw your FAQs which tell me to go into My Account section to download the Plugin. I tried that but it still downloads the old version of the Plugin, as I can see the changelog text file

(12/22/2015) - 1.2.79

I need to update it to GP 1.3.27 which is current, and the automatic update doesn't work.

Thanks,
