Okay, I've noticed that some people (including myself) are having trouble with canadianAssassin's hack.
Well, I've found my waay out of that hole and I want to help you too.
FILE CAN BE FOUND HERE: Crossfire Hacks - MPGH - MultiPlayer Game Hacking
1. Download the file.
2. Open PerX injector.
3. If it is not already there, make sure that it says it will inject it into crossfire.exe
4. Keep the injection on automatic.
6. Click browse. If it does not automatically pull up CanadianAssassin.dll, this is what you do. For those who it does - this does not apply to you.
7. Create a new folder. You can do this in many ways, i find the easiest to be open up perX, push browse, and push the create new folder button.
8. Name it what you want, just make sure you remember. Put this folder on the desktop for easy access.
9. In winrar, extract the CanadianAssassin.dll into your new folder.
10. Go to desktop and open the new folder to make sure that the dll is in it.
11. Go to perx, push browse, go to yuor new folder, and click on the dll.
12. Open crossfire, and VOILA!!!!!!!
Thank me if this helped!
