Guide missing data for HDPVR tuner until 4pm today

I'm not sure how this happened but the guide for my hdpvr tuner that resides on my primary box has lost all the data in its guide. "No Data" is what shows up for all the channels until 4 pm today. Last night when I saw it I went in a added a channel so the guide would update. Checked in the help and it said it had just updated so I looked back in the prog guide and still wasn't there. Figured it might take a while, decided to wait till this morning. Still nothing, but I did notice it has shows as of 4pm this afternoon just nothing till then. I actually did the add channel waited, checked help, the removed the channel and looked again last night.
Something I did yesterday afternoon was to turn off my encoder server and build a new one on a WHS server, and its part of the guide is there. I had to manually remove the old entries from the .properties on the primary as removing the sources didn't remove those entries for some reason.

I just decided to upgrade the hdpvr drivers to the one that came out last week which takes a reinstall of the source and after about 1/2 hour the guide data finally showed up.
