For this lesson, we will show you how to debug a problem that can occur when you import a unity package that was developed in a newer version of Unity than you are currently using. The problem is that you might be missing all the UI component script from the objects in your package. If this is the case then there are two options for fixing this problem. You can either go back through each object in the package and replace the UI components or the better option, just update your project to the new compatible version of Unity.
