Black screen – Love Nikki-Dress UP Queen Review

Go to open the app and I just get a black screen, I’ve tried opening through the App Store , restarting my device, sitting and waiting for the game to load up but nothing happens. Was in the process of updating but it never went through and no longer shows an option to update, I don’t know what’s wrong or what to do and I love this game have put a lot of work and money into and would hate to lose everything and don’t think I would want to start all over again ... please help.
