Will not let me buy full version – Paranormal Pursuit: The Gifted One HD - A Hidden Object Adventure Review

I downloaded this game about a week ago, played through the demo until it asked me to buy the full version. So I bought it. But it will not let me keep playing. When I hit the "already purchased" button it says there are no accounts linked to this game. But when I try to buy it again it says it's already been purchased. I tried uninstalling and downloading and buying it again but it still says it's been paid for and will not let me continue in the game. Can you please try to figure out what is going on? Thank you!!
