I ordered a theme for 80$ and activated it thru the wordpress dashboard to get a full featured product. But for some reason the same machine need to be re-installed. Now when I reinstall the website, it is no more possible to activate it. It is the same server/machine.
I see nowhere where it is possible to delete an activated site and reinstall the licence.
Thanks for your help, the ticket I submitted to envato has not been answered for a while.
