Hello, group.
Well, I'm glad to say that i finally got it going.
I did two things, both suggestions from this thread.

I added some calcium carbonate, which I actually had on hand, but had
forgotten about.
that alone, however, did not start the fermentation.

I had a pack of Lavlin EC, and I rehydrated that in a cup of very warm
water mixed with a bit of sugar and yeast energizer, and a couple of
tablespoons of the must. within a couple of hours it was bubbling
away. I added a couple more table spoons. Next morning, still
fermenting, so I added 1/4 cup. At lunch, another. By supper time,
1/2 cup. Before bed, another 1/2 cup. When I woke, 1 cup. At lunch,
I swirled it all around and gently poured it on top of the must in the
primary. By supper, it had a nice cap as all the cranberry sludge was
pushed to the top. . . . aaaaah, the sweet sweet smell of fermentation,
and the joy of not wasting my fruit or my work!

Thanks again for the ideas....
Have a blessed Christmas, y'all!
