BTC Flame Apps uninstalled and cant re download error 24

[AC Question]

I finally managed to get the app to install for my daughters Furby Boom and this morning its saying the app is not installed (but icon remains on home screen) when I cleared all the cache it still wont work. It just says error -24.

There is a tonne of space available for it so i'm frustrated and cross. Please can someone help me.
