Can only select /k, g/ – Drillaby Pro Speech Therapy Game - SLP Edition Review

Since I purchased Drillaby Pro I have had nothing but problems. Initially, it would crash as soon as I tried to open the app. Now, even though I purchased the Pro version, I only have the option of selecting /k, g/ phonemes. Previous Review: I just purchased this a week ago. Whenever I open the app and hit "Play", the program crashes and I'm back to my home screen. Help! Have deleted and uploaded several times. How can I get my money back?
