I would double check and make sure you have the leatest managed directx runtimes installed for the included .EXE. I didn't include the bitmaps because they are an embedded resource.
titex.bmp is the name of the texture for the logo in the background, feel free to try getting rid of all the loading and rendering code for that quad, or replace it. The other texture is for the ball. Feel free to add a custom ball bitmap texture instead. To do so, just add the bitmap to the solution as an "Existing Item." Afterwards, right click on the bitmap in the solution explorer, and select properties. Then in the topmost dropdown menu select "embedded resource." Good luck!
