Revoke License

I deleted all content on my website to start fresh for a new project. Upon doing this it deleted my plugins as well. When trying to reinstall newsomatic I get the following error "Plugin already registered on another domain, please revoke it to move the license to this new domain: http://xfo.wpt.temporary.site" It would appear my license somehow switched to a temporary site. I need this revoked so I can switch it back to my own website. Thanks :)
