Has anybody successfully unregistered their copy of GPO4? If so, how exactly can it be done?
Hi and welcome to the forums!
Are you worried about installing GPO4 to a new computer? You only need to drag and drop the keycard with your GPO4 license onto your new ARIA Player installation if that is the case. There really isn't any un-registering to be done from your computer besides un-installing if you don't need it on an older machine.
