The primary thing you’ll need to make sure is that you’ve loaded up the PPPoker Card Catcher first, and clicked START CATCHING before you have the PPPoker client application or your emulator running. If you do not do this, you likely will not have proper hand history capture, and thus a HUD will not load.
If you’re not seeing a HUD, Close Drivehud, your PPPoker client app and/or emulator and the PPPoker Card Catcher. Open Drivehud up first, open up your PPPoker Card Catcher and click START CATCHING. Then load your PPPoker client application and/or emulator. Wait for one full hand to be played before you see a HUD.
