Cant play anything!!

I used this app for a while and I adore it. This app was the best thing I had on my iPad mini, i even bought the extra sounds. However, now after the latest update the app no longer works. I cannot play any sounds and the screen becomes untouchable. Ive tried deleting the app and then installing it but nothing seems to work. Id rerate this app 5 stars if not for this problem.
