Analog Stats Page - Missing Stats

For my stats directory (Analog 6.0) that DH provides us, I seem to be missing stats from April 2005 to October 2006. The stats were fine in October 2006 because I checked but it looks like they were erased in those months. What gives?

I haven’t tampered with in anything in the server and it has remained unchanged except for uploading a few graphics and basic html pages. This is a shame that I will never get those stats back.
