Major crashing issue

So, a few updates ago, after updating, my game info seemed to be reset. When I opened the app it showed a random character like the first time I opened the app. I attempted to start the first episode(the only one unlocked at that point) and it just crashed entirely. This is all it's done since. I was hoping an update would fix it but that seems to not be true. I'm using an iPhone 4S and just updated again ten minutes ago.
