var response = login.TryAutoLogin();

if (!response.IsSuccess) // failed to automatically log in
{
    var email = Console.ReadLine();
    var pw = Console.ReadLine();
    response = login.Authenticate(email, pw);

    if (!response.IsSuccess)
         throw new Exception(response.Result.ToString()); // failed to log in
}

// This session variable is the result of logging in and is used in MLaunchOption, in the Launch part below.
var session = response.Session;

System.Net.ServicePointManager.DefaultConnectionLimit = 256;

//var path = new MinecraftPath("game_directory_path");
var path = new MinecraftPath(); // use default directory

var launcher = new CMLauncher(path);

// show launch progress to console
launcher.FileChanged += (e) =>
{
    Console.WriteLine("[{0}] {1} - {2}/{3}", e.FileKind.ToString(), e.FileName, e.ProgressedFileCount, e.TotalFileCount);
};
launcher.ProgressChanged += (s, e) =>
{
    Console.WriteLine("{0}%", e.ProgressPercentage);

var versions = await launcher.GetAllVersionsAsync();
foreach (var item in versions)
