  • ok I've asked you to stop duplicating questions. You are essentially asking the same thing over and over and over again.

    Aryan responded to your original question here

    If that's not enough then please edit that question to add more details, or close it and open a fresh one with a proper explaination of what you are doing so people can help you - then edit that question to add details.

    I'm going to close this one yet again as another duplicate, if you keep posting the same thing over and over again I'm going to start just deleting them.
