Im mad

I got this app before it was removed from the app story. After that it started to not work so I deleted it. the at the same time it was off the App Store it gets updates. due to the update before this one. every time I try to go in to it it goes black and kicks me out. But since its iOS 8 I cant update it because I have iOS 7.1.1 if they fix it to work or at less lower it to iOS 7.1. I will give them 5 star rating. Thanks for your time.
