"Reference Rasterizer was requested but is not available.
Please make sure you have DirectX SDK installed".

Can somebody help me?

Sounds like you need to download and install DirectX from Microsoft's webpage. Just do a quick google search for DirectX and it'll be one of the top links.

Question is, how in the hell does your computer NOT have Dx installed? Is it a new computer ? ::scratches head::
