Have you started hand importing using 'Play Poker -> Get Hands While Playing' in PokerTracker 4? Is PokerStars creating the hand history files on your computer? If it isn't creating the files in the default location then try setting a custom location instead (e.g. C:\StarsHH). If that's not the problem then please turn on 'Enable Logging' in PokerTracker 4 via 'Configure -> Options' and then restart PokerTracker 4. Next reproduce this issue by playing on a PokerStars table for a few hands with 'Play Poker -> Get Hands While Playing' active and then attach your support bundle to a
Support Ticket. The support bundle is created via the 'File -> Create Support Bundle' menu option in PokerTracker 4.
