Dave's Public Hack

OK Dave's Public hack seems to be the best one out there for now, so I've decided to use it. But I've encountered many problems, and have tried many solutions. First of all, I've tried the default injector, Perx, and OMFGZ. This is what happens for each injector.

(btw i named my .dll yomama.dll and my default injector is called yomama.exe.)

Have Windows XP
DirectX 9
Virus Protection is off
Obviously have .net framework :P


Default Injector
I start yomama.exe, wait 5 seconds, then start the game. Sometimes I get an *** error but most times the Gameguard window comes up then disappears, I check my processes and Crossfire exited.

Perx
I do automatic injection with yomama.dll into crossfire.exe. I get a successful injection every time, and then the gameguard window pops up. Just like the default injector, crossfire shuts down.

OMFGZ
Exact same thing as the Perx injector.

Can someone help me out with this? Like I've used other hacks before, and this one is extremely simple. But for some messed up reason, Crossfire never starts.

Thanks for your help
