TC Helicon finally responded to my email.
They have provided more detailed instructions on the website, with a link under my question.
I suppose it's available to everyone now.
They did apologize for the slow response, saying they have a reduced staff and unusually heavy load.
I'll try the upgrade again when I get the unit home, probably Friday.
At first glance, I don't see anything set up differently than what I was doing, but I will be meticulous in following the directions.
I'll let you know what happens.
Thanks,
DonM
