Serviio

I am installing a new pc, and want to move my pro license, but don't know how to .

Can anyone help ?

Do you still have the license file? If so, simply load it into your new Serviio installation. If you don't have the file any longer, send an email to Zip at sales(at)serviio.org from the same email address you used to purchase the license, and he can send you a new file.
