@adarkz,
I see you did not read those rules, to which I linked, very carefully - you missed the part that says:

"

Do not repost the same question if the previous thread has been locked - particularly if you merely reword the question to get around one of the prohibitions listed above

"

Do NOT start another thread on this - our patience has limits.
