Thanks for the replies. Got it figured out - somehow on the Access Control tab in Tivo Desktop's Server Properties, the Roamio was unchecked. Not sure how that could have happened since it was fine a few days ago. Anyway, I re-checked the box, restarted Tivo Desktop, and everything is now fine. Actually, what I've now done is checked the option that allows Full Access to everything rather than selective access (I have 4 boxes networked). Hopefully that will prevent a recurrence.
