Please make sure you are
saving and importing PokerStars tournament summaries as well as the hand histories. We recommend that you have Tournament Summaries set to save in PokerStars (Settings -> Playing History -> Tournament Summaries) and set to import into PT4 (in Configure -> Sites & Import Options -> PokerStars).
If you have not been saving tournament summaries and/or have incorrect results you can request a CSV playing audit from the PokerStars software. PokerTracker 4 will import that file and update your results information accordingly. To manually import that file when you receive it select "Get Hands From Disk" after clicking "Play Poker". For any tournaments with incorrect data you can also
update the information manually using the Tournament Results window.
