Hello Joel,
thank you for purchasing the PRO version. There is no license key needed.
The PRO version is a completely different plugin from the FREE version (which you downloaded from wordpress.org)
Please go to the my account page on this site and login using your email and password you used during the checkout process. https://theweb-designs.com/my-account/
If you don’t remember the password then enter the email and reset the password.
After you login, you will see the link to download the plugin.
Download it and then login to your site, deactivate the FREE version and install the PRO version which you just downloaded in last step.
Activate the PRO version.
That’s it.
its very easy and if you have any issue just let me know.
thank you again for buying the PRO version 🙂
Regards,
Abu
