Getting thrown out of app

Ok SAS Is an amazing game hands down
Ive had it ever since it came out
But the thing is everytime I try playing any mode at all and either on(singleplayer or online) it wait like 5 seconds and throws me out of the app.
Its really Aggravating
I love the game but please fix this
I recommend this game to everyone I see and stuff and I want people to play

And for all those people that are looking for an amazing and entertaining game that you can play for hours
This is the game for you
