Plug-in Update Message - Must reset license

for Justified Image Grid plug-in, I get this message in WordPress:

Automatic update error! This purchase code has already been used on another host! You need one regular license for each different site. You can setup your staging area in a subfolder to have autoupdates on both installations. Contact JIG support to reset your license (only the username is needed).

I am only using this plug-in on this one site

How do I get my license “reset”?


You will need to contact the author @Belcovio of that plugin for support

Here is their support information -
