What version of PostgreSQL are you using? PokerAce Hud does not yet support PostgreSQL 8.3.x and the database cache will not work. You will either need to:
1. Revert back to PostgreSQL 8.2.9 (the latest supported version)
2. Temporarily disable your database cache until we are able to get 8.3.x supported. Options->Preferences->Databases, uncheck 'Use Database Cache'.
If you're not using 8.3, 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.
