Zero data in guide

I have no clue where to begin to try and fix this. My guide data in the DVR and all the devices connecting to it shows there is no data present.

There are no Guide settings to think of, that i know of, so i have no clue how to force a guide refresh.

I looked in my log and see where two or three days ago it shows it started trying to download guide data and but then there is some error about no enough space on device. those two events have occurred a couple dozen times since.

This makes no sense to me bc there are hundreds of gigs of space left on the HD hosting my DVR. i assume that's where the guide data is stored. if it's stored locally on the host machines drive it too has plenty of space.

someone please help, i apparently have been missing days/weeks of recording and just now noticing it bc the guide has not be refreshing

The guide data is stored on the same volume as your OS. Can you open Finder and see how much space is available?
