Bodog/Pokertracker/Dogwatch help requested

I bought the dogwatch license but am still running the demo version of PT. When I click "force import" on PT I get these messages:
"Starting import, 3 files found..."
"Import Finished - 3 file(s) read - 0 new hand(s) were imported."

I try to look at my stats but it still shows zero hands.
So it seems to be able to find the hand histories but can't interpret them? Any thoughts on what might be wrong?
