Hi i need to change my name domain, but impossible to find the reissue licence buton on my licence.... impossible to reset my old domain name to the new one.
Maybe you made your license permanent for this domain before, that would remove the reissue license button.
Or it is already reissued. Did you try to enter the license in the JReviews license page on your new domain?
If it's not already reissued, submit a ticket with the license number and Alejandro will reissue it for you.
