Breeder's Cup Heartbreaks

I watched the replay after work on friday and after watching Secret Circle win that race, I had thought I had the Pick 5. Excited, I looked at my account balance but it did not reflect any increase. I had not known that #7 Congo in the second race had been DQ'd off of an objection that he did not instigate. How does he get DQ'd and Goldikova get off scott free???
