Your AQTime license installed on this machine is activated for a limited number of machines that can run this copy in the network simultaneously. At that, the number of AQTime instances running on each machine is not limited. This message appears when you are trying to run AQTime on your machine and the total number of computers running AQTime exceeds the number of user licenses you have. As a result, your instance of AQTime will be terminated. To run AQTime on your machine successfully, close it at least on one machine.
