Hack Help win7 64 bit

Hey I'm running win7 64 bit and I have tried multiple hacks with multiple injectors running CA and the injectors as administrator in compatability mode and nothing works!!! The .dll's are injected properly yet they fail to actually work in game please help (antivirus avast 5 and Microsoft essentials)

thanks in advance

Disable ur antivirus
Maybe the hacks are out of date
disable your firewall
the injector sux

Hacks are probably out of date, or your computer is incompatible with them, as my old one was.
