Do you have the correct file/folder configured in Options > Preferences > OnGame?
ATTENTION: Windows VISTA users, you must read this...Is ongame INSTALLED in English, not just writing hand histories in English?
Try clearing the ongame hand history / database file by clicking "Clear Databases" on the PTO auto import window. (Make sure you have imported everything from it first).
If it still isn't working, Please enable logging, reproduce the problem on a single table and play 30+ hands, and send the PAHud.log file via the
Support system so that we can review your configurations and troubleshoot the issue.
