Seems the version you're using isn't compatible with Blender.
Your Blender is 2.69, here is a list of previous versions of Source Tools that should be compatible with your version.
I strongly advise on updating to the latest version of Blender, since it's very optimized and overall better.

That screenshot's error implies that you're using Blender 2.69. What version of the Blender Source Tools are you using? Not all plug-in versions are compatible with all Blender versions.
