I bought a wordpress theme that cost $1000 and the owner deactivated my license for no good reason. He claims I violated the terms of service by downloading the theme on sites that I do not own but I do own all sites that I downloaded the theme onto. He refuses to let me prove that I own all sites. He claims his back-end software found other ip addresses and different hosting accounts. Looking for advice on what I can do to either get a refund (year later) or get my license back (possibly through an attorney).
