Purchase yields no puzzles! – Battle-Boats Extreme Review

When I purchase Puzzle pack 1, it says you've already purchased this (do you want it again for free) and then says purchase successful, but no puzzles appear. The store continues to say that Puzzle pack 1 is available for purchase. It's an endless loop! Can someone respond if this can be fixed?
