Wont Launch

Im not sure if there was a recent automatic update or what the problem is, The game wont seem to launch now. All I get is a black screen and it just sits there. I also really hate the fact that I have to wait a day to play each new level with the latest update, that is unless, I want to pay to unlock each level. Bad Rovio...bad!!!
