Fix urgently needed!

I downloaded Episode 5, but since then, if I launch the app I only get to the "Tap to Continue" screen, then the screen goes black and freezes. So I cant get to the menu to choose any episodes! I had purchased all episodes when this game first came out, so right now, I cant play the game AT ALL! Given the price of these episodes, this is completely unacceptable. What is Telltale Games doing about this?!
