WILL NOT OPEN! – ProStudio - Music Recording App Review

I have to give this app one star. At first, it would not import songs from my music library, now it will not open. I had it installed on my iPhone 4. Now I have an iPhone 6 and it still doesn't work. It has to be the app. VOCALIVE works well on both devices. This issue should be fixed. I feel scammed. ?
