I got this issue some time ago and read notes from others with similar issue: licenses sometimes get lost on a computer. This means that after you put licenses from the cloud to your machine, licenses disappear after reboot.
I am not a big computer expert, but from what I understand, licenses are attached to MAC address, which is a device’s unique identifier, assigned to a network interface controller. So, when Waves Central moves licenses to a machine, the licenses ‘remember’ the MAC of that machine to ‘recognize’ it when want to use the plugins. On some machines, in rare cases, probably the WiFi adapter messes up with the network card, so the machine is not always reporting the same MAC. At least it looks like that
As a result, next time the licenses will see different MAC on the same machine, so they stop working. In Waves Central it appears like the licenses were moved to a devise which is ‘not connected’.
A solution for me was to use recover function to restore my licenses to the cloud, and then I moved licenses to a USB stick. Now they are in a more safe place
Correct me if I wrote something wrong. And hope this helps
