Are you playing regular cash games on PartyPoker? If you are then you should note that while you are seeing player names at the tables the player names in the hand history files used by PokerTracker 4 have been
anonymised by partypoker. As a result PokerTracker 4 now defaults to show session stats instead of lifetime stats for the anonymous players but it will still track your own results fully (your own name is not anonymous in the histories). If that isn't your issue then please restart PokerTracker 4 using the logging enabled link on your Start Menu, reproduce this problem and then report it via our
support system with your log file so we can investigate that for you. You can access the log file by clicking 'File --> Show User Data Folder' in the main PokerTracker 4 window and the file we need is the text file called 'PokerTracker4' or 'PokerTracker4.log' that is in that folder.
