Thank you. Can you please enable logging in PokerTracker 4 via 'Configure -> Options -> Enable Logging'.
Next restart PokerTracker 4.
Move your backup file to the root of C:\
Run the restore process again and uncheck everything under 'Optional Files'.
If the database does not restore successfully save/send us this file in a
Support Ticket before you restart PokerTracker 4:
C:\Users\{Windows Login}\AppData\Local\PokerTracker 4\Logs\PokerTracker4.log
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.
