Auth field on cable card tivo info

I have a Tivo Bolt that I bought used.  It worked fine for the previous owner.  When I hook oit it (after having Comcast pair the cablecard) I get a v52 error, 0 signal strength, and no picture or sound on any channels.  A Comcast technician came out yester, checked the signal strength on the end of the coax that plugs into the Tivo, and it was very good.  I talked to Tivo and was told that the cable card (by the way I tried 4 different ones) has to be a 2014 or newer, and has to have an auth field on the screen with the con, etc.  I hecked a Tivo Roamio Plus I have hooked up and it has the auth field.  The  cable card info for the one in the bolt does not have an auth field and I'm pretty sure the cards that Comcast gave me are ancient.  Is the missing auth field the reason I get the 52 error and no picture or sound?
