When cloning an OS or VM with Pulseway pre-installed, the unique identifier for the endpoint gets duplicated across each system, causing the behavior you're describing. If you open regedit, and navigate to: 'HKLM:\SOFTWARE\MMSOFT Design\PC Monitor', you should delete the 'ComputerIdentifier' key on each of the duplicated endpoints. The client will recreate a new identifier, and register the system correctly using another license.
