title: Wrong Password using WhatsAPINet for send WhatsApp in WinForms C#
body: <p>I am thinking of creating an Windows Forms C# application (in Windows 7, Visual Studio 2012, .NET Framework 4.5) and I want use any WhatsApp API to send messages. </p>
  
  <p>I have found this .NET fork of the PHP interface <a href="https://github.com/venomous0x/WhatsAPI" rel="nofollow">WhatsAPI for PHP</a>  by Dídac Pérez Parera: <a href="https://github.com/perezdidac/WhatsAPINet" rel="nofollow">https://github.com/perezdidac/WhatsAPINet</a></p>
  
  <p>I have this test code:</p>
  
  <pre><code>string nickname = "WhatsAPI Test";
  // 34 = Country Code
  // 6xxyyzzmm = mobile number
  string sender = "346xxyyzzmm"; // Mobile number with country code (but without + or 00)
  string imei = "MY IMEI ANDROID THAT I GET USING *#06#"; // MAC Address for iOS IMEI for other platform (Android/etc) 
  
  var wa = new WhatsApp(sender, imei, nickname, true);
  string countrycode = sender.Substring(0, 2);
  string phonenumber = sender.Remove(0, 2);
  
  if (!WhatsRegister.ExistsAndDelete(countrycode, phonenumber, imei))
  {
    PrintToConsole("Wrong Password");
    return;
  }
  </code></pre>
  
  <p>I test, but always I get "Wrong Password"</p>
  
  <p>In my mobile phone, I have installed Whatsapp. It's a Android 4.0.</p>
  
  <p>Any suggestions about it?</p>
