Ansys HFSS COM Engine non-responsive

Hello all,

I have a problem with Ansys Electronics Desktop 16.2. When I try to simulate a model, the COM engine starts but immediately becomes unresponsive. The error I get in the message window is:
[warning] Com Engine non-responsive since 22:23:31, September 08, 2015. Can be due to CPU intensive processing or network problems. If persisting for long, manually kill the com engine process and restart analysis. Retrying..... (10:24:31 PM Sep 08, 2015)
[error] Machine localhost: Engine terminated unexpectedly, or machine reported error or was inaccessible. (10:25:31 PM Sep 08, 2015)


Any ideas? I am running HFSS on windows.

Thanks in advance!
J.

-------------------UPDATE
I have tested the current machine configuration and it fails because it "Cannot connect to RSM service". The service is running normally though...
