ardu-stim 1.21 load fails

I have sucessfully used ardu-stim v0.3.0 for testing a NO2C board I built a number of years back, powered from a Win 10 Pro pc. Resurrrecting the project and noted that Ardustim has been updated so downloaded latest v1.21, Connect Arduino nano to PC, First, run the old 0.3.0 exe to confirm it still works - all is fine. Repower the nano, run 1.21 exe and select correct port, attempt to run the firmare upload . LEDs on the nano blink, message "preparing to burn firmware" appears then 'X upload to arduino failed". Repowering, and then going back to the 0.3.0 exe and ardustim works as before.

any suggestions as to what I need to do to get 1.21 working?
