C# - .NET 4.5 Speech Recognition problems

Hello, my name's Jake Cross! I've recently ran into a problem when I upgrade to Visual Studio 2013 running .NET 4.5. I've been using Sharp-develop for programming C# with the .NET 4.0 framework but and it was working fine with the exact same code. I'm unsure why this is, I don't believe it's because of my new laptop and I've made sure my mic was set to the default audio input device. Here's the code. 

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.IO;
using System.Speech.Recognition;
using System.Speech.Synthesis;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace J.A.R.V.I.S
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        SpeechRecognitionEngine jListen = new SpeechRecognitionEngine();
        SpeechSynthesizer jTalk = new SpeechSynthesizer();

        private void Form1_Load(object sender, EventArgs e)
        {
            jListen.SetInputToDefaultAudioDevice();
            jListen.LoadGrammar(new Grammar(new GrammarBuilder(new Choices(File.ReadAllLines(@"C:\Program Files\Stackoverload\Jarvis\Grammar\English.txt")))));
            jListen.SpeechRecognized += new EventHandler<SpeechRecognizedEventArgs>(jListen_SpeechRecognized);
            jListen.RecognizeAsync(RecognizeMode.Multiple);
        }

        void jListen_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
        {
            string speech = e.Result.Text;

            if(speech == "hello")
            {
                jTalk.Speak("Hi");
            }

        }
    }
}

Thanks ahead of time!
