WILL NOT OPEN!

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 doesnt work. It has to be the app. VOCALIVE works well on both devices. This issue should be fixed. I feel scammed.
