Can you please open this file with NotePad:
C:\Users\{Windows Login}\AppData\Local\PokerTracker 4\Config\Pokertracker.cfg
If you do not see the AppData folder in Windows File Explorer then see
this guide. Under the [General] heading there will be a line like this:
Logging=N
Change the 'N' to 'Y' if it isn't already:
Logging=Y
and save the change. Next start PokerTracker 4, reproduce the issue and open a
Support Ticket with the following file attached:
C:\Users\{Windows Login}\AppData\Local\PokerTracker 4\Logs\PokerTracker4.log
