I was doing fine, enjoying the game immensely, until today. Trying to access game, I am meet with demand to download an upgrade . . . With no means by which to download the upgrade! Tried uninstalling and reinstalling game, no luck. This is a problem I have run into before and it is really beginning to sour my enjoyment of any mobile games. If a game needs to be updated, is it too much to ask for a tab that allows us to do just that without jumping through even more hoops?
