If the price does not even update with a z-program then either your z-program is very poor or you must have caused an update failure, then you should provide more and better info.
As you did not at all respond to the information provided by Dibyendu I have to assume that you did not even read the note, can it be that you cannot access it, why don't you tell it then? Don't you have colleagues who have access and can download it for you?
