I admit, I havent played this in a while. When I redownloaded it I tried to login to my Rovio account, I put my email in to the "Forgot My Password" box, click ok, and it crashes the game. The old system was better, and the best part...
I CANT GET MY IN APP PURCHASES BACK!!
Its a waste of money and time. I do not recommend it. I will change this if they fixed it.
