1. Error initalizing 3D Hardware . Now software will be used....

2.Could not initialize DirectX Graphics.You mush have installed Directx 8 or better and a 16,24 or 32 bpp Desktop to run this sample.

I HAVE directx9.0c and 24 bpp.!!

what graphics card do you have?
if its nvidia then there is a known driver problem. search the forum as lapis has mentioned the needed driver.

I had that once, and I have to tell you that it will not work.
