I'm a level 11 ranger and im trying to buy Dark Forest Campaign. When i click Purchase it casys "confirm Your in App Purchase. Do you want to buy one Dungeon Campaign: "The Dark Forest" for $1.99? I click Buy. It Pops up with You Can't Purchase This. You must purchase the app that this item is for before you can purchase the item. Nothing i can do lets me be able to buy the new content. Anyone know how to get around this? Clearly i have the app its for if im playing it.
