[Elecraft] KAT500 - Utility not working

[Bill Wiehe via Elecraft]

I discover a problem with my KAT500 in that the Utility shows that no Software is loaded. It still received signals from the computer as I can control it from HRD but I cannot make changes via the Utility. The cable Interface Cable shows only "flashing red" light. To this point I have confirmed the computer com ports are functioning properly. The cables are all attached. I have changed the cable input point to confirm it is not the computer port that is the problem. I even tried to reload  my previously saved configuration to no avail. The Utility screen continues to say that no software is loaded. And yes I reloaded the Utility program on the computer. Any help or insight would be appreciated as I have never had a problem to this point. Thank you in advance.Bill - W0BBI
