Just a note that a Win10 update I got today May 13, "broke" all of my rig control and digital mode software, including RigBlaster drivers, FLdigi, HRD and WSJT. Not sure what happened. Spent about an hour trying to trouble shoot the problem and couldn't find what it was. Basically the error messages I was getting indicated the software couldn't find my transceiver, couldn't access the RigBlaster, etc. Tried updating drivers, reinstalling drivers, changing com ports, etc and nothing seemed to work. Finally rolled back to the previous version of Win10 and that restored all of the functionality.
