Activated DB does not work from one to another day

Activated DB does not work from one to another day. How can this be?

Assuming it is not a trial licence that expired, check for other system changes and particularly MAC address changes.

Try a new activation with the same licence, do you get the same activation code or a new one?

I don't think the MAC changed. However, the activation code is different now and it works. Very strange.

Examining this issue further against activation logs found a report of a new MAC address for your activation on 2024-09-18 at 20:40 GMT.
