what eazyed420 is trying to say is you need download source sdk. go in under your tools(in your libary you have choose games or mods then you choose tools) find source sdk and download it and im sure it will work

+ 1 to what Aprilfools says. You must install the source sdk from the tools library or any mod you get will not function.

what I think they meant was the Source SDK 2006\2007. The Normal Source SDK is used to make maps and stuff like that for source games.

You just need to install the old SDK Source Engine (as the new one is too updated to run it on).

Just go to your Library, select Tools from the selector, scroll down and you'll have 3 options;

SDK Source
SDK Source Base 2006
SDK Source Base 2007

Last I checked it worked with 2006, so install that first. If it works, peachy. If not, just install 2007 as well.

Hopefully that helps clear that up!
