Paid for the full version – Animal Sounds - Fun Toddler Game Review

I paid for the full version of this app. It stopped working so I deleted it then re-downloaded it and now it says I have to pay to buy the full version again! I'm not happy!!! I need a refund or a way to download the full version without paying again!!!
