Purchasing problems – Adventures of Laura Jones lite: the hidden invention of Nikola Tesla Review

I love hidden object games but this one keeps asking me to buy the app when I've already bought it. Am I paying three dollars (which is way to much for an app anyways) for this app every time it asks me after every segment of the game? Fix this.
