Should I buy a licence for my test site on local wamp server?

Hi,
I just import from production site to my local wamp server and I can’t update the the7 theme. I get a message : Theme was remotely de-registered.
Is it because the Theme is not register for this site? And should I bought a licence?
Regards

no, for using the theme in your localhost server. If you are facing any license issues to use in your production server then please contact your purchased theme author and let them know. Theme author will help you to fix the issues.
