Code:
//==Add all your Staff ids $INSTALLER09['allowed_staff']['id'] = array(1,2,3);
//== Add ALL staff names before you promote them
$INSTALLER09['staff']['allowed'] = array( 'System' => 1, 'DooMFeaR' => 1, 'Bller' => 1);
the "1" means it's allowed. the ids are written on the line above.
i think this is the reason.
