[time-nuts] Lucent RFTFm-II-XO- Lady Heather question-having issues

I downloaded the latest version 4.00 beta of lady Heather on my win XP laptop. 
Installation creates two icons on my desktop. One says KE5FX TBolt (Seattle USA) and has the lady Heather icon and the other has the icon and simply says Lady Heather. 
When I try and open the Lady Heather icon (not TBolt one) an error box pops up and says Can't open com port:\\.\COM1 and will not open the software. Opening the TBolt version icon instead will open the program. 

What did I do wrong?
Also the RS422 adapter shows up as com6 and I see in the instructions to change a command line to /6 for com6 but I am not sure where to find the command line.

Thank you.

This usually works, but some hardware serial ports have voltage threshold issues reading data from the device (the RS-422 signals don't swing as much as the RS-232 ones do).  All my USB-serial dongles work well, but I have had some issues with genuine hardware serial ports.
