problem while using hacks

hi guys i tried using hacks and when i do i just cant kill anyone
i tried different dlls and different injectors but none worked..
i shoot someone in the head for a whole minute and he does not die..


any suggestions?
(i have win 7 X64 and im using injector in compatibility mode win xp sp3 and running it as admin
also tried without compatibility mode same thing)

Hmm vieleicht laggt der hack und in moment sind die server down fur mich!
