Please restart PokerTracker 4 using the logging enabled link on your Windows Start Menu, reproduce this problem and then send your log file to is in a
Support Ticket:
C:\Users\{Windows Login}\AppData\Local\PokerTracker 4\PokerTracker4.log
If you do not see the AppData folder in Windows File Explorer then see
this guide. Once you have the log file you can try going to this folder:
C:\Users\{Windows Login}\AppData\Local
Rename the 'PokerTracker 4' folder there to something like 'PokerTracker 4_backup' - do not delete the folder, just rename it. This change is going to cause your existing custom settings to be reset like you're using PokerTracker 4 for the first time (but they are backed up in the folder you renamed above). If PokerTracker 4 is able to start with a default user folder then please
zip/compress the 'PokerTracker 4' folder you renamed and attach that to your ticket as well.
