Wont Open Anymore

I used to love this app - great when you unexpectedly need a bright light or when you need to magnify something too tiny to see. Also great for an elderly friend who cant read menus without it. Now, for whatever reason it simply refuses to open. I even deleted some of my less-used apps to free up space, which was a waste of effort. So annoyed - now this app is 100% useless to me
