My GUI stopped working?

Okay I bought this asset online so I would like not to show the whole script. The problem is this asset stopped working when I updated from unity 5.0 to 5.1.2. The script is for a controller GUI interface but it seems to be giving me an error :> NullReferenceException: Object> reference not set to an instance of an> object> UnityEngine.UI.Selectable.Select () on this line of code : selectedOject.GetComponent ().Select (); so there is a null reference and its no longer recognizing the child objects as buttons is what I'm assuming if you want to have a better look at his set up he has a short video On youtube : [HERE][1] I would like to continue to use this script and continue updating Unity.
