5.7.24 invalid license - windows update auto reboot

have one server (win 10) and 3 terminals. 2- win 11 and 1-win 10

all were working fine. windows update caused all systems to reboot overnight. this morning all were in demo mode.

re licensed server. its fine. the windows 10 terminal licensed as well.

the 2 terminals with win 11 all come back with invalid license.

the issue is the message server keeps auto starting on the 2 terminals.

so in windows services.msc i set sambapos message server properties to disable.

uninstalled the service with the samba tool.

log in to sambapos and check local settings for the correct message server address and says connected.

run activate license from samba market (also tried from samba folder)

message says license installed successfully.

and get this:

what am i doing wrong?

everytime you run the licensing program the messeging service starts.
