I had some negative in the last few weeks… I also only promote US books.
I blame the MLB season, seems that all the sharks make their money with MLB.
But college football and now NFL is making me back the $$$ 
In your case, ya $80K ? I assume you mean gross… so your aff commish is in the neg by about $20K ?
That does seem odd… is it with one player?
Also, being that far in the negative… I recommend not promoting them… start fresh with another sportsbooks… right now you want to take advantage of all the people hyped about NFL and NCAAF… you dont wanna be stuck diggin yourself out of a big neg commission.
