I download a standard asset in Asset store called “Standard Assets for Unity 4.6”, and my unity version is 5.3.0. Why i import 2D folder of the packages, unity occured a error:

(1).Broken text PPtr in file(Assets/SampleAssets/2D/Animator/2DCharacterAnimator.controller). Local file identifier (110283043) doesn’t exist!

(2).Assets/SampleAssets/2D/Scripts/Platformer2DUserControl.cs(2,25): error CS0234: The type or namespace name CrossPlatformInput' does not exist in the namespace UnitySampleAssets’. Are you missing an assembly reference?

Lady and gentleman, please help me please!! Thank a bunch!!!

Download the standard assets for 5.x.
