The HUD is working at PokerStars Euro tables for me.
Please restart PT4 and play a few hands at a single Euro table and then attach the PokerTracker4.log file from C:\Users\yourname\AppData\Local\PokerTracker 4\ (which you can access from the PT4 File menu) to a
Support Ticket along with a
screenshot of the table window and the hand history file.
Thanks.
