If you are using the new Beta version of the Winamax software please restart both Winamax and PT4, and then go to Configure > Sites & Import Options > Winamax and click 'Auto Detect'. If the Hud still doesn't work after that please open a Support Ticket and report your problem so that we can check your log files and see what is going on.
So if understand correctly PT4 is working with new Winamax Beta version. I tried as well, I can see that hands are tracked correctly, but HUD doesn't appear on the tables... I tried delete and auto detect in Site configuration, I tried to add it manually. Hands been tracked, but no HUD on the tables. Should I fill support ticket? Btw on older Winamax version everything is fine.
