D3Dx9_43.dll NOT FOUND?!

When I try and inject a hack I get this error, never any other time.

[Story of what happens.]
I start up my injector (run as administrator) and put in everything needed, inject to Engine.exe, put the .dll in the files to inject, tick close after inject, tick auto inject, then start up Combat Arms from the Nexon website. Then just about instantly, I get the error shown above. When I click OK. It will then start the game, and the hack won't work.
