For Send/Recv hooks and other code modos there are like 3 HShield functions that are required to get fixed (atleast 2 weeks ago it was this count). One checks Engine addresses (memory manipulation message) and next two functions checks for modos in EhSvc (There's problem in function of anti-hacking message).
But for best output I would recommend emulate function of EhSvc that generates an Authentication packet and Heart-Beat packets. I never found that func as I'm just using hooks and I'm happy with it. Maybe in future.
