One cable box will no longer pause and rewind Live TV.

Hi,

My first floor cable box  froze up (first thing this morning) while watching Live TV.  I unplugged the unit, waited a minute and then plugged it back in.  It came back on but now displays the message, "Instant Replay Card Removed." (See the attached photo.)  I searched for this error online and saw that people have indeed had this issue suddenly pop up on some boxes - that rebooting might fix the issue.  I have rebooted multiple times and also did a system refresh yet the issue continues - it claims the instant replay card was "removed" and the box no longer supports pause and rewind, etc.  Recordings, interestingly, do still pause and rewind but Live TV now just gives that same message if you try to pause. My main box on the second floor still works perfectly (Live TV still pauses, etc) so this appears to be either a firmware (update?) or hardware issue with the one box...

Are there any other steps to try or does this box need to be replaced?  I am hoping there might be some other troubleshooting steps but I have a feeling something has gone wrong with this unit. Thanks.
