NativeToolkitManager not found!

I have implemented Prime31's NativeToolKit from the UnityAssetStore. To get my scripts to see the NativeToolkitBinding I had to copy that file to my Scripts folder. I have been able to load a native view and for that matter hide the native view. What I am having issues with is attempting to load a new scene after my native screen. What ends up happening is I go back to the same Unity Scene.

 - (IBAction)startGame:(id)sender {
     
     // TODO: Add code to verify age.
     [[NativeToolkit sharedManager] sendMessage:@"loadScene" param:@"PlayScreen"];
     [[NativeToolkit sharedManager] hideViewController:self];
     
    
 }
