I've checked and your subscription has already been cancelled. The Table Ninja II subscription is clearly marked at purchase time as a free trial that you opt into and you can test the opt-in procedure by visiting the
PokerTracker 4 purchase page again.When one purchases PokerTracker and chooses the free month of TableNinja II, it will notify you before checking out and then again on your order confirmation email that choosing to not cancel before the end of the free month means you want the subscription to continue.
