How do I stop a singleton from trying to load itself again when I change scenes?

I am working on a Kinect project and I use a wrapper (this one: http://wiki.etc.cmu.edu/unity3d/index.php/Microsoft_Kinect_-_Microsoft_SDK ).

There can be only one instance of the Kinect sensor, but it tries to make a new one when I try to load a different scene. This causes it not to work anymore. The problem stems from these lines of code:

     private static KinectInterface instance;
 public static KinectInterface Instance
 {
     get
     {
         if (instance == null)
             throw new Exception("There needs to be an active instance of the KinectSensor component.");
         return instance;
     }
     private set
     { instance = value; }
 }

And the Awake() function:

 void Awake()
 {
     if (KinectSensor.instance != null)
     {
         Debug.Log("There should be only one active instance of the KinectSensor component at at time.");
     throw new Exception("There should be only one active instance of the KinectSensor component at a time.");
     }
     try
     {
         // The MSR Kinect DLL (native code) is going to load into the Unity process and stay resident even between debug runs of the game.  
     // So our component must be resilient to starting up on a second run when the Kinect DLL is already loaded and
     // perhaps even left in a running state.  Kinect does not appear to like having NuiInitialize called when it is already initialized as
     // it messes up the internal state and stops functioning.  It is resilient to having Shutdown called right before initializing even if it
     // hasn't been initialized yet.  So calling this first puts us in a good state on a first or second run.
         // However, calling NuiShutdown before starting prevents the image streams from being read, so if you want to use image data
         // (either depth or RGB), comment this line out.
         //NuiShutdown();
         
         int hr = NativeMethods.NuiInitialize(NuiInitializeFlags.UsesDepthAndPlayerIndex | NuiInitializeFlags.UsesSkeleton | NuiInitializeFlags.UsesColor);
     if (hr != 0)
         {
         throw new Exception("NuiInitialize Failed.");
         }
         
         hr = NativeMethods.NuiSkeletonTrackingEnable(IntPtr.Zero,0);
         if (hr != 0)
         {
             throw new Exception("Cannot initialize Skeleton Data.");
         }
         
         depthStreamHandle = IntPtr.Zero;
         hr = NativeMethods.NuiImageStreamOpen(NuiImageType.DepthAndPlayerIndex, NuiImageResolution.resolution320x240, 0, 2, IntPtr.Zero, ref depthStreamHandle);
         Debug.Log(depthStreamHandle);
         if (hr != 0)
         {
             throw new Exception("Cannot open depth stream.");
         }
         
         colorStreamHandle = IntPtr.Zero;
         hr = NativeMethods.NuiImageStreamOpen(NuiImageType.Color, NuiImageResolution.resolution640x480, 0, 2, IntPtr.Zero, ref colorStreamHandle);
         Debug.Log(colorStreamHandle);
         if (hr != 0)
         {
             throw new Exception("Cannot open color stream.");
         }
         colorImage = new Color32[640*480];
         
         double theta = Math.Atan((lookAt.y+kinectCenter.y-sensorHeight) / (lookAt.z + kinectCenter.z));
         long kinectAngle = (long)(theta * (180 / Math.PI));
         NativeMethods.NuiCameraSetAngle(kinectAngle);
         
         DontDestroyOnLoad(gameObject);
         KinectSensor.Instance = this;
     }
     catch (Exception e)
     {
         Debug.Log(e.Message);
     }
     enabled = true;
 }
