Help Extracting SMD Tools Script for Blender!!!!!

I am trying to apply custom models to TF2 skeletons using Blender. I am following this tutorial(http://forums.steampowered.com/forums/showthread.php?t=1536668) but I need to get a script out of SMD tools by extracting it with winrar, but for some reason I get errors instead of a script. Anyone know why?

Could someone maybe send me the script so I can move along with learning how to do these projects? My version of blender is 2.7beta.
