Help how to articulate the logic

In this piece of code

private void wb_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
        {
            if (wb.Document.GetElementById("login-email") != null)
            {
                wb.Document.GetElementById("login-email").InnerText = settingsForm.tEmail.Text;
                wb.Document.GetElementById("login-password").InnerText = settingsForm.tPassword.Text;
                Method_1("button luxury")[0].InvokeMember("click");
            }

               CallMethodAfterDelay(KrysomahHunting, 5000, tm);

                if (wb.Url.AbsoluteUri == "http://www.moswar.ru/metro/" && wb.ReadyState == WebBrowserReadyState.Complete)
                {
                    wb.Stop();
                    method_2("c", "Выследить Крысомаху")[0].InvokeMember("click");
                    Method_1(new string[] { "button" })[0].InvokeMember("click");
                }

        }

When the program comes to the method 

method_2("c", "Выследить Крысомаху")[0].InvokeMember("click");

throws Exception ArgumentOutRangeException

I supposethat this couldbe caused by 

private void wb_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)

Heconstantly checks.Ifapagethatexecute methods .And because the method once already done its job, there is no longer the values

And so we get an exception ArgumentOutRangeException. Help how to make the logic for this case!

What if you add a check in on that method call?

var method2 = method_2("c", "...");
if (method2.Count > 0)
    method2[0].InvokeMember("click");
