Есть ли ошибка в методе FindElement (By by) Selenium RemoteWebDriver или я делаю что-то не так в своем коде ниже?

Question

Программа зависает при попадании в строку FindElement () в функции GetValue

class Program
{
    static void Main(string[] args)
    {
        Uri huburl = new Uri("http://selenium-hub:4444/wd/hub");
        DesiredCapabilities capabilities = DesiredCapabilities.Firefox();
        capabilities.IsJavaScriptEnabled = true;


        RemoteWebDriver myDriver = new RemoteWebDriver(huburl, capabilities);
        myDriver.Navigate().GoToUrl("http://mycompany/main.asp");

        CheckUserRegistered(myDriver);
    }

    public static void CheckUserRegistered(RemoteWebDriver oSeleniumWebDriverSession)
    {
        string sUserName = "test-01";
        if (oSeleniumWebDriverSession.PageSource.ToLower().Contains("some text"))
        {
            oSeleniumWebDriverSession.FindElementByLinkText("Register Now").Click();
            oSeleniumWebDriverSession.FindElementByName("fname").SendKeys(sUserName);
            oSeleniumWebDriverSession.FindElementByName("lname").SendKeys(sUserName);
            if (GetValue(oSeleniumWebDriverSession, By.Name("ReferenceIndicator")))
            {
            oSeleniumWebDriverSession.FindElementByName("ReferenceIndicator").SendKeys(sUserName);
            }
            oSeleniumWebDriverSession.FindElementByName("company").SendKeys(sUserName);
            oSeleniumWebDriverSession.FindElementByName("postcode").SendKeys("mycompany");
            oSeleniumWebDriverSession.FindElementByName("email").SendKeys(string.Format("{0}@mycompany.com", sUserName));
            System.Console.WriteLine("Not Found");
            System.Console.ReadKey();
            oSeleniumWebDriverSession.FindElementByCssSelector("css=input[type=submit]").Click();
        }
    }

    private static bool GetValue(RemoteWebDriver myDriver, By by)
    {
        try
        {
        //this is where it locks up.
            myDriver.FindElement(by);
        }
        catch (NoSuchElementException Ex)
        {
            System.Console.WriteLine("Not Found");
            System.Console.ReadKey();
            return false;
        }
        return true;
    }
}
