guide not functioning properly

This morning when I woke up I noticed that the guide only gave information until 4pm today and wouldn't scroll any further. I figured the issue would resolve itself but when 4pm arrived all I could see was "no data" for every channel. After resetting the box twice, the guide finally came back but now it won't scroll past 4am. The guide is also not showing all of the data it usually does. For instance, when i press the "info" button on my remote I usually can see actor and release date information for movies/tv episodes but now that information is missing. Is there a problem with the guide data or is my box toast?
