اول حاجه هنخش علي Forward.cs
وبعدين هنضيف دهم

==============================
using System;
using System.Text;

namespace COServer.Network.AuthPackets
{
    public unsafe class Forward : Interfaces.IPacket
    {
        byte[] Buffer;
        public enum ForwardType : byte
        {
            Ready = 2,
            InvalidInfo = 1,
            Banned = 25,
            WrongAccount = 57
        }
        public Forward()
        {
            Buffer = new byte[52];
            Writer.WriteUInt16(52, 0, Buffer);
            Writer.WriteUInt16(1055, 2, Buffer);
        }
        public uint Identifier
        {
            get { return BitConverter.ToUInt32(Buffer, 4); }
            set { Writer.WriteUInt32(value, 4, Buffer); }
        }
        public ForwardType Type
        {
            get { return (ForwardType)(byte)BitConverter.ToUInt32(Buffer, 8); }
            set { Writer.WriteUInt32((byte)value, 8, Buffer); }
        }
        public ushort Port
        {
            get { return BitConverter.ToUInt16(Buffer, 12); }
            set { Writer.WriteUInt16(value, 12, Buffer); }
        }
        public string IP
        {
            get { return Encoding.Default.GetString(Buffer, 20, 16); }
            set { Writer.WriteString(value, 20, Buffer); }
        }
        public byte[] ToArray()
        {
            return Buffer;
        }
        public void Deserialize(byte[] buffer)
        {

        }
        public void Send(Client.GameState client)
        {
            client.Send(Buffer);
        }
    }
}
===========================================

وبعدين هنخش كمان على LoaderEncryption

وكمان وبعدين هنضيف دهم

وكمان هنخش علي  Authentication.cs
بعدين هنحط بدل اللي عندك

=======================

بعد كده هنخش على Constants.cs

GameCryptographyKey = "z1Sf34V7z6AV13uA",

بعدين انت هتغير الكود ده اللي عندك

وحط ده

=========================================

وده الباتش بتاع اللودر

وكده تمام وان شاء الله كل جديد هانزله هنا
