Bolt & Comcast Cablecard

So I got my new Bolt, set it up with OTA and really liked it. Today we got the cable cards from Comcast and it did not go well. First we were told it would take a while, then when we called back, we heard it was a TIVO "service provider" issue, that Tivo had to send something to the box. Called back a third time and was told my two new cablecards were bad. Now I am waiting for a technician on Saturday.

Any experience or suggestions for others who have done this?
