Injection Problem..?

Hey I have the Faith Injector, and the Crossfire Hack.dll.
the boxes are checked for the setting, and when I load up CF and start game, the popup box shows when it injects.

But in game, I try pressing the num pads, but it doesn't work. :S
Help? Am I doing something wrong?

If the success box shows up then the hack should work. What is your OS?
Do you remember where you got the .dll? The thread that contains the download should have all the info you need.
