You can use PokerTracker 4 with PokerStars but not TableTracker as it is no longer available for purchase on our website. All PokerStars clients use the same software so please make sure things are setup correctly:
PokerStars Configuration GuidePokerTracker 4 only supports English so hand histories need to be saved in English (PokerStars Client -> Settings -> Playing History -> Hand History) and the PokerStars client needs to be running in English (PokerStars Client -> Settings -> Global -> Language -> English).
