I upgraded to pro for the meta box, currently, I have downloaded the free version, which used to say go pro and no longer says that now as I have paid for a subscription to this service. How do I activate the meta box free version app I downloaded. All my products are already mapped I just need to change how I charge customers which is per product and that is blocked by the go pro option. I have also received the email to active my meta box and it confirmed at the top that it was accepted

The free version is always free and don't need activate.
I guess you mean activate to remove the notice asking to upgrade. To do this, go to My Account page, get the license key and go to your WP admin > Meta Box > License and enter it.
Note that the menu Meta Box > License is only available if you use at lest one premium plugin on your site. If you don't use any premium plugin, e.g. only the free version, then there's no way to detect that you're a premium user and thus, no way to remove the upgrade notice.
