We have been having issues with our registration server. This situation has caused the date error you are experiencing when trying to use PAHUD. We are currently in the process of restoring functionality to everyone's PokerAce HUD registration codes. We expect this issue to be resolved within 12 to 24 hours. Once your code has been fixed, it will register again. Please continue to try opening PokerAce HUD once an hour or so to register your key with us. Once the issue has resolved, your code will work again successfully.
One documented workaround is to reset your computer's clock to May 24th while PokerAce HUD is closed, then open PokerAce HUD. Before playing, reset your clock to the current date, and PokerAce HUD should continue to work (if it ceases to function, you can keep the old date, but your hands in PokerTracker 2 may contain the wrong date). We do expect this issue to be resolved shortly, at which time you will want your date and time set correctly, but if you are intending to play a session imminently, this workaround might be useful to you.
If you have lost your key, you can get it again here:
