Whenever i try to start a game, it will only show an error message saying that there is something wrong with this dll.
Error message: _The program can't start because d3dx9_39.dll is missing from your computer. Try reinstalling the program to fix the problem._
Recently i have reinstalled my Windows 7.
I have already reinstalled my DirectX, downloaded the d3dx9_39.dll and put it everywhere from system32 to league of legends folder, launched it all from administrator and also reinstalled my League.
