Performance center 9.52 - Failed to initialize load test error message

Hi,

PC Version 9.52

I'm getting the below error while starting a load test,

Failed to initialize load test!
Error: Unable to run load test.
Event: -2147219770
Details: Activation attempt [1]: Unable to configure group runtime settings.

Description:Method [ActivateRun]: Unable to activate load test run: reason=[Unable to configure group runtime settings]: [ErrCode 0x80010105, Source Interop.ORCHIDACTIVESESSIONLib: The server threw an exception.] The server threw an exception. (Exception from HRESULT: 0x80010105 (RPC_E_SERVERFAULT))

Any solution for this?

Thanks in Advance
