Can't see the words??? – Touch Detective 2 1/2 Review

So I've had this app for a while and I've bought all of the content, but I frequently replay it because it's a great game. Today I tried playing and the game is running fine, but the words aren't visible. They're just empty speech bubbles? What's going on? Maybe it's not fully supported by the new iOS updates? Please fix this!
