If you're referring to NoteCaddy stats not displaying for PokerStars players, please make sure you process notes in NoteCaddy (You can click NC → File → Reset Notes, and then click Yes to let NC process them).
Also you should make sure that NoteCaddy is not filtering PokerStars hands out (NC → File → Filters).
If you're talking about PT4 stats not appearing (like # of hands), then I would recommend to write a support ticket, or to write in the general PT4 forum: https://www.pokertracker.com/forums/viewforum.php?f=58
It shouldn't have anything to do with NoteCaddy in this case, and I'm unsure how it should be solved without more information. If the hands are in your database, they should be displaying on your HUD.
