Rigging problem in SA

[ThePrince]

Hi

i'm trying to change the player's head following this tutorial:

 

 

but everytime, either the head shows with the original game texture (even when using TXD editor to change the texture), or the game freezes!

 

 

Here are the Files : https://www.mediafire.com/?71x42wc06c69rh2

 

Thank you
