The TC guy phoned me today. He said he was also the one that answered my email query.
The version on the website is the final one now.
He was extremely nice. He said there are TWO service reps for all of North America. And that's not just for the Harmony M, that's for everything they make.
No wonder they are slow to respond!
I haven't had a chance to try the upgrade again. I won't have another day off until Sunday.
