I am using unity 4.5.1f3 and using the Vuforia sdk 5.0.5.I have downloaded the sample project from the Vuforia site.When I tried to run the sample of Imagetarget project,it asked to add license key.Then I added licensed key to the app.Then when I runned the project again its showing me and error
MissingMethodException: Method not found: 'UnityEngine.Behaviour.get_isActiveAndEnabled'. Vuforia.VuforiaAbstractBehaviour.UpdateStatePrivate (Boolean forceUpdate, Boolean reapplyOldState) Vuforia.VuforiaAbstractBehaviour.Update ()
The Image marker detection can run but the camera video doesn't show in the background. can anybody help me solving the issue?
