If your name doesn't exist in the database then you haven't imported any hands into PokerTracker 4 yet. All iPoker skins use basically the same software so is your iPoker skin saving hand history files?
iPoker Configuration GuideThe folder where hands are saved needs to be added to PokerTracker 4 under 'Configure -> Sites & Import Options -> Site Configuration -> iPoker Network':
C:\Users\{Windows Login}\AppData\Local\{iPoker Client Name}\data\{iPoker Screenname}\History\Data
If the client isn't automatically detected by PokerTracker 4 you can manually select the correct folder using 'Add'. Once that is setup you can test this on a table by clicking 'Play Poker -> Get Hands While Playing' and after taking a seat you should see your hands being imported.
If you do not see the AppData folder in Windows File Explorer then please refer to
this guide. If that doesn't get things going please report this to us in a
