I updated Affiliates Pro fine, but cannot update the Integration. When I navigate to your site at https://www.itthinx.com/plugins/affiliates-woocommerce/ there is no download link for it, and only makes mention of the Lite version.
When I click View Details on the plugin page, there is an error stating it cannot find it.
