Hi all
I need to deregister my old MacBook. Had due to software problem to reinstall MacOs on both my MacBook and my Mac Mini. I forgot to deregister Marginote. I got to reinstall it on the MacMini but on my MacBook I get that this license is already activated and cannot activate Marginote 3 to do the upgrade to Marginote 4.
Is there any way to deactivate the old copies or reset my licences.
Many thanks
