Please restart PokerTracker 4 using the logging enabled link on your Start Menu, reproduce this problem and then report it via our
support system with your log file so we can see the details of the error. You can access the log file by clicking 'File --> Show User Data Folder' in the main PokerTracker 4 window - the file we need is the text file called 'PokerTracker4.log' that is in that folder. In addition to the PokerTracker4.log file can you please also attach your 5 latest PostgreSQL log files from:
C:/Program Files/PostgreSQL/x.y/data/pg_log
or here
C:/Program Files (x86)/PostgreSQL/x.y/data/pg_log
(x.y refers to the version of PostgreSQL installed on your computer).
