Injecting Problem.

Ok..

I'm having a problem with injecting .dll files into my crossfire.exe, whatever injector I run, it says the file is injected but when I press the hotkeys for the hacks to work ingame the game doesn't respond, except for one hack I use but I can't mention that one, it would be advertising.

So, what could be the cause of this?

I'm running Windows XP SP2 professional, I've got DirectX9 and .net framework 2.0 installed.

Please help.

Thanks.
