The new version of Babstats Chronos for BHD v1.2.0.4 was flawed.
Consequently Baboon has released another update which fixes the upload problems some people were getting.
Also included now is the 'track hosts stats' switch which means that if you are playing and serving but not actually playing, you can leave the computer safe in the knowledge that your stats wont be ruined by having your performance tracked as you stand in a server map after map getting no kills and one death every time.
