Stopped working as soon as we bought to unlock all levels – Math Games for Kids & Toddler Review

I first downloaded the free app to see if my daughter would like it. She did enjoy the level 1 and asked me if I could unlock all levels. I proceeded to unlock all levels and poof. We cannot launch the app anymore, trying to launch it closes it immediately. Tried reinstalling with no success. Thumbs down all the way
