   Error with app when used to run....
  This one application I found online awhile ago used to run on my comp, nothing has changed except updated directx. And now I get this error, "This application has failed to start because d3dx9_24.dll was not found. Re-installing the application may fix this problem." I know I have this dll because I see it in plane sight anyone know why?   
  Well that dll was the D3DX dll released with the February DirectX SDK. April was d3dx9_25.dll and June d3dx9_26.dll. There are also debug versions (with a d on the end).   ;  I have all the sdk's and runtimes it just not run? lol
