Sorry Spence - I missed the bit in your first post (and later ones as well!) about using a real serial port
So your screen dumps show that you have V3.0.0 firmware in the MJLJ and you're trying to run the V3.2.0 configurator - which doesn't work - and trying to load firmware V3.2.0 into the MJLJ on COM3. And as Brent says, you should probably be going to V3.2.1 firmware and V3.2.1 Configurator, but that's not the issue here.
If the V3.0.0 Configurator downloads and uploads maps OK then I'm a bit stuck for ideas

apart from:
- your MJLJ isn't on COM3. hc08sprg.exe will report an error if the COM port doesn't exist, so that seems OK. Are you really, really sure the MJLJ is on COM3
- I have had problems with the reset ACK not being recognised occasionally. It almost seems that I'm not connecting the power quick enough (ie it needs a rapid application of power, which defies a lot of logic). If that happens I just Control-C the DOS command and rerun it - it invariably works fine next time I power up the MJLJ while the PC is waiting for the reset ACK
I'll keep thinking....
