Update causes constant force closes. iPhone 4S :-( – Santa Zombies Vs Ninja Review

Please help!! Very frustrated! I've been playing this game for a couple of months and have loved it. Kind of addictive fun! I have gotten to level 50, have 111,500 darts and 300+ bombs accumulated. Since I installed the update a couple hours ago, it force closes all the time. I cleared all programs, cycled my phone on and off, everything I could think of. Still no change. It was always a bit glitchy. Since I first installed, snowballs never worked, it would force close if I threw a bomb during leveling up, but these issues didn't stop me from enjoying the game. Please resolve, I want to play it, and, I don't want to lose my progress, dozens of hour playing.
