Crashing...

I used to play this game all the time, and just tried playing again yesterday. The app would crash when I opened it, so I re- downloaded it and restarted my iPod (5th generation). It would let me in the app and would let me play but only as one of the already set default characters. When I tried to comment or change the character/name it would crash again. pleeeease fix
