Hello,
Regarding your query, as everything is fine with the latest version of the theme once please verify that the license you have brought has the reached to the expiration date or not
All of our premium themes comes with the initial 1 year of Subscription i.e. you can download the updates till 1 year of purchase date. But after one year, you will need to renew your subscription in order to continue downloading updates.
Regarding your query, the issue might have raised due to the expiration of the license of the theme.
So, please make sure that the license has not been expired.
Hope this clears the confusion.
If you have further query, let us know.
Thank you.
