So a few months ago I tried to install just dance 2 dlc by following the guide entirely. That eventually led to me having to reinstall ios56 (I think). After I reinstalled it I tried going in to just dance a few days later, but the game would not load and just showed a black screen, the same thing happened with Pokemon rumble which also uses the same iOS (i think). So I am asking what I should do to get these games to work again.
