All questions related to installations, configurations and maintenance of Advanced Host Monitor (including additional tools such as RMA for Windows, RMA Manager, Web Servie, RCC).
RMA Manager does not perform tests. So, it looks like RMA is connected to RMA Manager but not connected to HostMonitor. Am I right?
Do you see "HM is not connected" message (red background) on RMA's status bar?
Have you specified correct parameters for RMA -> HostMonitor connection?
