All my npcs and ppl are invisible

I cant play -- all my npcs and players are invisible. I ve restarted both client and my system and its been 3 days but i havent been on to mess with it. The only thing I havent done is redownload client.

I would definitely try that. Seeing as nobody else is having the problem it must be client side, first thing that comes to mind would be having your graphics all up to date but seeing as you saw them before I would say just re-install the client.
