Hi,
Sorry for the delayed in response.
When you purchase our theme you will get lifetime access to the theme. But the theme updates and the support will only be valid for a year. If you renew it after a year you will get updates and support for another one year. But if you do not want to renew it then still you can use our theme without any issues.
The renewable notification starts popping on the screen before a year is complete. It’s just a notification you can ignore it if you don’t want to renew it.
Now in your case, don’t you have the theme that you have downloaded when you have purchase the theme?
Thanks
