The App was Great until all of a sudden it stopped working properly

The Apps concept is marvelous. At the intermission this app was amazing until it just stopped working properly. It force closes when I click on browse to change the wallpaper. It force closes when i try to change the unlock and lock sound. It force closes when I press my lock screen home key. It force closes when you are entering in your password or sometimes even before that! This app is having some serious problems. I wasted money and it hurts!
