Highly Disappointed

I would love to leave a review but in order to to that I would have to have been able to use the app. I paid for it, it downloaded, I tried to use it , and NOTHING. The first initial screen came on and then it goes to nothingness. If I could give it zero stars I would. How do I get my money back or get help???
