webcamtexture makes unity 5 crash

I have a project where i'm projecting my device's camera onto a plane using a webcamtexture. I've had it working before, but with unity 5 it keeps crashing whenever i press the play button. I have the following script on the plane.

  using UnityEngine;
 >     using System.Collections;
 >     
 >     public class backgroundScript : MonoBehaviour {
 >     
 >         private WebCamTexture backgroundTexture;
 >     
 >         void Start () {
 >             backgroundTexture = new WebCamTexture ();
 >             backgroundTexture.requestedWidth = 1920;
 >             backgroundTexture.requestedHeight =
 > 1080;
 >             backgroundTexture.Play ();
 >             GetComponent<Renderer>().material.mainTexture
 > = backgroundTexture;
 >             
 >             Debug.Log ("camera image width = " + backgroundTexture.width + 
 >                        " camera image height = " + backgroundTexture.height);
 >             //StartRecording ();
 >         }
 >     
 >         public void StartRecording(){
 >     
 >         }
 >     
 >         public void StopRecording(){
 >             backgroundTexture.Stop ();
 >         }
 >     }

I've also commented out the line: backgroundTexture.Play(); and it didn't crash, so i'm assuming this is the cause of the problem.
