This request is [highlight]not cool![/highlight]
There is no good reason to unpack a pServer client. You don't develop a client that is in use on a server for your own use because you won't understand the modifications in it. You don't steal the work of others! (which they are still actively using)
If there is a feature in there which you would like help understanding how it may be achieved, see how far you can get on your own, then ask them politely, showing that you have the skill and they can help you get there quicker or just be an arse about it. If they choose to be an arse, come and ask people here showing the same level of skill and understanding and describing the "feature" for those of us who may not know of the development.
If you are trying to cheat on their server (the probable reason the client is protected and most common reason for wanting to unpack clients) [highlight]get off RaAGEZONE[/highlight] and go play in some other nasty butt forum!
