I got an iPad Air for Christmas, had to start a new

Hi, I just got an iPad Air for Christmas. I’ve been playing AB Fight on it in the days since, and all of a sudden it is crashing in the first few screens. My screen name is ToneDeaf. I tried to send a message on the help site, but it wouldn’t accept my id. I’m using iOS 9.2, which it says is current. My email is [email protected]. I also play Fight on my iPhone under the name StarryKnyt. I am wondering if having two different games going could be the problem? Thanks
