Стандартный код выдает ошибку

CrmAuthenticationToken token = new CrmAuthenticationToken();

CrmService crmService = new CrmService();
crmService.CrmAuthenticationTokenValue = token;
crmService.Credentials = System.Net.CredentialCache.DefaultCredentials;
AppSettingsReader appSettings = new AppSettingsReader();
crmService.Url = appSettings.GetValue("CrmSdk.CrmService", Type.GetType("System.String")).ToString();

task my_task = new task();
my_task.subject = "my_task_1";
Guid t_guid = new Guid("A64664F4-E699-DD11-B4E0-00A0C5B316E9");
Owner t_owner = new Owner();
t_owner.Value = t_guid;
t_owner.type = EntityName.systemuser.ToString();
my_task.ownerid = t_owner;
Guid accountId = crmService.Create(my_task);
}
}

Ошибка идет на шаге Guid accountId = crmService.Create(my_task); такая:
