If you mean Aurora then Zoom HUD support was added sometime ago for that. Can you please try starting the PokerTracker import (Get Hands While Playing) before launching PokerStars and if it is not working after doing this, please uninstall PokerStars and re-download and install PokerStars to see if that fixes it. If you have any further trouble
enable logging, reproduce this problem and then send your log file to us in a
Support Ticket. You can access the 'Logs' folder with the log file by clicking 'File --> Open 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.
