Программная авторизация на сайте

Здравствуйте.Ребята помогите с проблемой,уже мучаюсь неделю, не могу решить
Суть такова: Нужно через программку на С# взять из сайта кое какую информацию.Но что бы туда попасть, нужно с начала авторизоваться.В этом и вся проблема,не могу авторизоваться.
Промониторил весь google, нашёл пару толковых пример, но у меня не получается
Вот мой код:

Code:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Net;
using System.IO;
using System.Web;

            logBox.Clear();
            VKLogin(tbMail.Text, tbPassword.Text);
        }
    }
}

Первый запрос проходит нормально.Сервер возвращает мне куки.Я беру его и вставляю во второй запрос.
А после второго запроса сервер не понятно как то для меня реагирует. Словил пакеты через Wireshark, скриншот на картинке нижу



Прошу помогите, нужно решить эту проблему.Спасибо.
