Selenium WebDriver c #: Doubt when leaving the catch

I have the following code, which occasionally, when placing an order, I skip a window pop-up indicating the same user that has orders in progress, you accept and continue with the order, but I do not the test ends Method _Productos.PedirProducto(); does not do anything if I use _Pedido.ComprobarPedidoEnCurso(); Thanks

Class Order

    public class Pedido : PageObjectBase, IPedido
        {

            //AceptarPedidoEnCurso
            [FindsBy(How = How.XPath, Using = "//div[@id='popup']/div[3]/p[2]/a/span")]
            private IWebElement _aceptarPedidoEnCurso;

     public Pedido()
            {
                PageFactory.InitElements(this.WebDriver, this);
            }

     public void ComprobarPedidoEnCurso()
            {
                try
                {
                    if (this._aceptarPedidoEnCurso != null)
                    {
                        this._aceptarPedidoEnCurso.Click();
                    }
                }
                catch
                {
                }
            }

Product Class

     public class Productos : PageObjectBase, IProductos
        {
            //PedirProducto
            [FindsBy(How = How.XPath, Using = "//div[@id='999990010430687']/div[2]/span/span")]
            private IWebElement _pedirProducto;
        }

    public void PedirProducto()
        {
            this._pedirProducto.Click();
            Thread.Sleep(TimeSpan.FromSeconds(3));
        }

Test Class

 [TestClass]
    public class TestPedido : AutofacContainer
    {
        private readonly IHome _Home;
        private readonly IPedido _Pedido;
        private readonly IProductos _Productos;

        public Test()
        {
            this._Home = AutofacContainer.AContainer.Resolve<IHome>();
            this._Pedido = AutofacContainer.AContainer.Resolve<IPedido>();
            this._Productos = AutofacContainer.AContainer.Resolve<IProductos>();
        }


        [TestMethod]
        public void Test_12()
        {
            _Home.GoToHome();
            _Home.Login1();
            _Pedido.RepartoADomicilioConRegistro();
            _Pedido.ComprobarPedidoEnCurso();
            _Productos.PedirProducto();
        }

        [TestCleanup]
        public void EndTest()
        {
            _Home.CloseWebDriver();
        }
    }
}
