Can't pair Roamio or Premiere with Charter

After 4 trips out by Charter techs in STL and several cable card swaps and hours spent on the web,
I have been unable to pair 2 of my Tivo's by Charter. Finally yesterday a tech told me that there is
an issue between Charter and Tivo's firmware keeping the boxes from being paired. I get all channels
except the premium channels like HBO and Showtime. On the cable card conditional access screen
CON = "YES" but VAL is always "?" I have other Tivo's and even the Premier was paired in the past
and all when smoothly. The tech said they don't pair now because of a firmware problem.

The tech said Charter and Tivo know about the problem and are working on it with firmware upgrades.
Does anybody know anything about this?

Thanks!
