Dear Konstantin,
We hope this message finds you well.
We wanted to follow up and check if you were able to resolve the issue. It appears that a license has already been registered, as shown here: https://prnt.sc/3yTKvYP289pE.
If the issue has not been resolved, would it be possible for us to remove the current registration and proceed with registering our license for testing purposes?
Please let us know how you would like to proceed.
Thank you for your time and assistance.
Best regards,
The 8Theme Team
