Hi Welcome to the forum. An OTA which commenced while you have been away has most likely upgraded the firmware to 1.00.20 on your box overnight when you powered the box back on. As a result you need to reflash with the latest firmware and update your packages (1.00.20 has changed the way housekeeping works).
Raydon was away on holiday when this happened but has posted a temporary link on AV Forums.
