Toon Basic shader turns objects pink in 5.3.4f1

Hello I recently updated unity only to be presented with this:

Everything was fine until I updated to unity 5.3.4f1 which I was using 5.2.2f1 until yesterday. Everything was fine until I switched scenes to update a script in it and now everything is pink in that scene even in the scene I was in before where everything was fine is now all pink. Also when I tried to re import it, all meshes that had materials with toon basic on flashed it’s normal textures then turned pink again. I hope you can help me if you need to see the shader source here it is:

Shader "Toon/Basic" {
	Properties {
		_Color ("Main Color", Color) = (.5,.5,.5,1)
		_MainTex ("Base (RGB)", 2D) = "white" {}
		_ToonShade ("ToonShader Cubemap(RGB)", CUBE) = "" { }

	SubShader {
		Tags { "RenderType"="Opaque" }
		Pass {
			Name "BASE"
			Cull Off
			#pragma vertex vert
			#pragma fragment frag
			#pragma multi_compile_fog

			#include "UnityCG.cginc"

			sampler2D _MainTex;
			samplerCUBE _ToonShade;
			float4 _MainTex_ST;
			float4 _Color;

			struct appdata {
				float4 vertex : POSITION;
				float2 texcoord : TEXCOORD0;
				float3 normal : NORMAL;
			struct v2f {
				float4 pos : SV_POSITION;
				float2 texcoord : TEXCOORD0;
				float3 cubenormal : TEXCOORD1;

			v2f vert (appdata v)
				v2f o;
				o.pos = mul (UNITY_MATRIX_MVP, v.vertex);
				o.texcoord = TRANSFORM_TEX(v.texcoord, _MainTex);
				o.cubenormal = mul (UNITY_MATRIX_MV, float4(v.normal,0));
				return o;

			fixed4 frag (v2f i) : SV_Target
				fixed4 col = _Color * tex2D(_MainTex, i.texcoord);
				fixed4 cube = texCUBE(_ToonShade, i.cubenormal);
				fixed4 c = fixed4(2.0f * cube.rgb * col.rgb, col.a);
				UNITY_APPLY_FOG(i.fogCoord, c);
				return c;

	Fallback "VertexLit"

Hello there, @CreeperSeth
I know you go an problem with a shading in unity3d… But i have an advice for you, go to and choice Assets/Import Assets/Characters/Effects/ToonShading (only)
If it doesn’t helped… Go delete this shader and re-import this, Hope this helps!
