To get help, you need to provide information. Why should anyone have to ask you all these questions to give you help? Why would you make it hard for people to help you? These forums are full of nice and helpful people but you gave almost nothing for people to help you. You made it harder than it has to be. It is also like trying to get directions from a guy that cannot speak.
