The Key for the License is tied to Database and the SambaMarket Login.
If I make a DB backup at my Venue, restore it on my Laptop, and happen to be logged in to SambaMarket with the incorrect User (a user registered for another DB - I think I have 4 IIRC), it will go into trial mode, because the User is registered with a different Key.
Are the Terminals (not the Server) Logged in?
Is the Server Logged in?
Curious to know, what happens if you:
Logout all Terminals, and leave them that way. The Key is in the DB anyway, which does not reside on the Terminals.
Reset Keys / Login on SERVER, and Activate, then Logout the Server and leave it that way.
