I just purchased PokerTracker 4 for use with PokerStars.
I installed everything and PokerTracker 4 does not detect PokerStars, so I provided the install location.
The help pages here and a few other places say I need to go into "Settings->Playing History" to enable hand history for PokerStars so that I can tell PokerTracker 4 about it, the problem is. PokerStars does not have this option in it's settings.
I would like to point out that I'm playing PokerStars with "play money" not real. I live in Connecticut and while online Poker is legal, there aren't currently any "officially supported platforms" in Connecticut yet, though PokerStars will likely be supported in the future given their ties with the casinos here in Connecticut.
Anyhow, I'm a bit frustrated that PokerTracker does not detect PokerStars, nor does PokerStars settings have the setting options that are required for PokerTracker 4 to function.
