Did I not explain it throughly for you?
Do you get what it is and what you can do once you have it in your hands?
Please respond if your question has been answered, then LOCK THIS THREAD so to not waste anymore people's time.
That is the job of what a forum does, not to have more and more people rant on about the same thing repeately.
