With PAH not running, delete the 2 cache files. C:\Program Files\PokerAce Hud\Data\Temp\DBCachexxx.*
Then restart PAH and this will force a full rebuild of the cache.
If that doesn't work, use the 'repair database' option in PT2 Utilities menu and try again.
If it still won't work after that enable logging, reproduce the problem and send the PAHud.log file via the
Support system so that we can review your configurations and troubleshoot the issue.
