Activation Issue Again

Just sticking up a ‘me too’ for this thread. No reply needed. S3W requested re-activation 5 minutes ago when I switched from my laptop to my desktop to continue writing my WIP. Never had an issue doing that before.
ISP has been working on their cables, etc, lately and we did lose the net twice at the weekend, maybe the internal addresses changes for the desktop. The Macbook and Windows laptop in the same building didn’t have this issue.
