After downloading the last "upgrade" I could not open Angry Birds. I tried off and on for the last couple of weeks. Finally, yesterday, it opened so I have left it open until I could at least get some scores on the board for Mine and Dine. Really frustrating - I'm afraid to close it for fear it won't open again. Not backed up either (my bad). Oh well, it's just a game...it's just a game...sigh. Hope there will be a fix for this problem. (iPod Touch gen2, 8gb, latest iOS). Any words of wisdom would be appreciated.
