cant update plugin

Im trying to update the product addons plugin to the latest version. i have enabled auto update and have the woo helper plugin installed.

I assume i need to enter my liscense key. So I followed the tutorial here https://docs.woothemes.com/document/woothemes-helper/
but i see no license tab to enter the key!

The error i get when i try to update is “An error occurred while updating WooCommerce Product Add-ons: Update package not available.”
