D2GS Crashes+Create games locked down

Well, i've made the register system manually since it started to happend and yes, it was fixed on that way

as i saw the problem was made because some kind of people joined with a kind of "hack/exploit/modification" to make my D2GS.exe crash or lock the game creation/join
