Do you have 2 versions of DirectX or DirectX SDK installed on your system?
Can you be more specific about what error message your are getting.

The SDK homepage seems to suggest you require the June'05 SDK in order to use it properly. This will most probably be due to it requiring the corresponding D3DX DLL (#26).

I thought the later SDK's installed all previous D3DX DLL's, but you might just have to go find the DX web installer and pick up all of the D3DX libraries.

They do should install all retail DLLs, but it seems my version (April 06) doesn't have all debug DLLs. I only have d_24 and d_30 (my version). I'd assume all SDKs are like that.

Hope this helps :).
