Game not launching

Please help me. My game keeps crashing randomly and a lot!! Every time I try to complete an sbc it crashes. When I enter the store it crashes. It's impossible to complete objectives because it keeps crashing. 3 days now! I'm so disappointed in my experiences with this game. Gameplay issues... the list is endless to be honest. I'm such a fan of EA but they have totally let me down on this one, unfortunately.
