Ошибка .NET справки бота Skype

Я пытался создать скайп-бота, который автоматически отправляет сообщение при отправке определенного ключевого слова. Кажется, он отлично работает в MVS, но когда я действительно запускаю его, я получаю эту ошибку. В вашем приложении возникло необработанное исключение;

************** Exception Text **************
