Cablecard assistance needed

I have a cablecard in a Tivo edge. that I've had for 5 years or longer The hard drive died, I've swapped it out and it is back functioning but I get V58 unauthorized errors on every channel it tries to tune. The page that used to exist on the comcast site to self service cabelcard repairing is of course now gone. Can I get this repaired?  That would make my wife very happy.

If the mods here also read/run reddit's r/comcast_xfinity channel, I've tried to post there under the same username and its constantly rejecting my posts.
