Invisible players

I've installed the patch to a friend of mine and he gets invisible player's skin. Does anyone know what to do?
Thanks

I have gotten that game couple of months ago. I will like to say that You will have t get it as online and update it as well. I am sure that You will find the player so far also visible mode. I hope that You will get it new. But Remember that You will update it right file extension. I wish that You will do it very well.
