Injectors

I'm having a hard time getting any injecting process. My problem is this:

I'm using: Druken Cheatah Injector

1. I select the "DLL" -> Evil Hook v1.dll
2. I select the "Process" -> iw3mp.exe
3. Press "Inject" -> In the second bar on the side of three dots (...)[INJECT]
4. It below in "More" appears and I click -> Successful Injection
5. Nothing happens! ! -> The COD4 was not open, but not open.

What should I do? Does anyone have any explanation for this?
I'm using Windows XP and disabling anti-virus.



p.s: Accept help for "TeamViewer".

Thanks all!

The COD4 was not open, but not open? Don't understand that..

If cod4 wasn't open how could you pick iw3mp as a process
