我的世界启动器代码不工作

我有一个minecraft客户端启动器，这没有启动minecraft。我在TeamExtreme尝试了这些论点，但是失败了。[原文匈牙利，现译]

发射器代码:

        private void button1_Click(object sender, EventArgs e)
    {
        if (textBox1.Text.Length == 0)
        {
            MessageBox.Show("please enter username!");
        }
        else
        {
            button1.Enabled = false;
            button1.Text = "loading";
            string appdata = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData);
            string teamcraft = appdata + "''.RedMineCraft''minecraft.jar";
            string tcfolder = appdata + "''.RedMineCraft";
            WebClient client = new WebClient();
            WebClient client2 = new WebClient();
            client.DownloadFileAsync(new Uri("http://www.redminecraft.eu/cliens/minecraft.jar"), appdata + "''.RedMineCraft''minecraft.jar");
            client2.DownloadFileAsync(new Uri("http://www.redminecraft.eu/cliens/servers.dat"), appdata + "''.RedMineCraft''servers.dat");

            File.SetAttributes(appdata + "''.RedMineCraft''servers.dat", FileAttributes.Hidden);

            bool folderExists4 = System.IO.Directory.Exists(tcfolder + "''resourcepacks");
            if (!folderExists4)
                Directory.CreateDirectory(tcfolder + "''resourcepacks");
            client.DownloadFileCompleted += new AsyncCompletedEventHandler(Completed61);
        }
    }
    private void Completed61(object sender, AsyncCompletedEventArgs e)
    {
        string userpath = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData);
