First of all, your picture is way to small.
Second, there is a list of hacks on the main crossfire page.
CrossFire Hacks - MPGH - MultiPlayer Game Hacking
Half way through this page, you'll see a bunch of threads with hacks.
You'll also need an injector. Download one from here.
CrossFire Spammers, Injectors and Multi Tools - MPGH - MultiPlayer Game Hacking
After that extract both the hack and the injector.
Open the injector, run as administrator.
Then after browse for the dll hack, add it to the list.
Set process to crossfire.exe
When HGWC has finished loading, then you inject from that moment.
Retake the screenshot of that error your getting. It's way to small. Upload it on imageshack or tinypic.
Also take a screenshot of this "socket error."
