Let's play a game, since gamesmanship seems to be the order of your day: what's the intent or scope of your questions --- for what purpose?

As you're being evasive (whether purposefully, or simply not thinking "big picture") it's kind of hard to help or guide you when you're not clear.
Btw, why do you call it "cracked"?
