Meh... ok. You need to include the directory to this file: d3dx9.h

If you installed directX SDK it will be in your program files. Here's the file location: C:\Program Files\Microsoft DirectX SDK (August 2009)

google a tut on how to add directories to your project. and add this exact directory to you DirectX SDK include file: C:\Program Files\Microsoft DirectX SDK (August 2009)\Include
