App update screwed up my apps I created

I bought this app month and a half ago. Was working fine. Today i was sent an update. I updated it and the apps I created when clicked appears a black screen. Sooooo Upset. Now when I try to create an app it wont allow me to create with my own image. Again so upset.

M.Mina about One touch call, Apps, home screen shortcut icon ( iFavorite Pro : for Instagram camera, Snapshat, WhatsApp and iOS7 ), v1.3
