Glad to help. Normally license activation works great, but there are things can interfere depending on setup and so forth. In any case, I am happy to help troubleshoot and hopefully resolve the issue asap.
Note: The rules here at WordPress.org prohibit any discussion of pro/premium versions, but no worries as you also have sent an email to which I will reply soon.
Also just FYI: usually people give the developer a chance to help before hitting them with a negative/1-star review. That way everyone (you, me, visitors, etc.) benefits from the information. In the future, please consider opening a support ticket if you have questions or need help, thank you.
PS: Here is a link to the plugin’s support forum.
