I am having this issue as well now that I've installed PT4 on a second computer.
The HUD works fine for Zoom PokerStars tables but not for regular tables. Hands are also importing fine, whether for regular or Zoom tables, but no HUD for regular. It's so frustrating.
I've copied the HUD settings from my other computer to the new installation so I don't think it's that. Can anyone help?
I can send some logs of course but I am not sure what they would show other than hands importing fine into PT4 but no HUD.
