Lois i hawe tested every think! I just take a clean source GS and Disable just
//InitHackCheck();

And i can enter with diferent serials on server! Because server GameServer Dont Check the serial numbers! 
Check this by your self! 

and this is about season 6 sources!

//InitHackCheck();
#define ENCRYPT_STATE 0
#define PROTECT_STATE 0

/\ no make difference about this

I dont what you did wrong but in default source its works.

Try change ServerVersion to test...

//InitHackCheck();
#define ENCRYPT_STATE 0
#define PROTECT_STATE 0
