What Happened???!!!!

Ive never had a problem with this app, infact its one of my favorites!! I use this at least once a day, EVERY day! Then all of a sudden, for no reason, when I try to open the app, it slams the door in my face and throws me out!! I even tried deleting and reloading in hopes of a fix but had no luck.
