I can't open boxes the game is hanging on me when I try to open them.?

Check that you have a stable internet connection as this is required. Close and re open the app to see if that clears the problem. If the problem continues there may be an issue with your game. If you have saved your account data by linking it to facebook or your app account then you can try reinstalling the game. Or you can try contacting the game support for help. Check the support page for contact details.
