Connection refused in DDUtil

DDUtil quit connecting I’ve read all the issues on the yahoo group, I’ve deleted Ddutil and reinstalled. I’ve ran the delete settings batch file, I’ve turned off the firewall, this of course was after restarting rig, pc and router. The program is talking to the rig, I see my frequency in DDUtil, I can control the kpa500 and kat500 as far as turning them on and off, standby and operate. But no auto drive and even though my flex control isn’t set up thru DDUtil, it get the same send error from DDUtil when I tune it. I’ve also removed and reinstalled my cat ports, everything else seems to be working, rig control from my logger, wsjt-x all working fine. I’m beginning to wonder if the problem is in SSSDR. Anyone else experienced this?
