A problem about Strumpy Shader Editor

A got a trouble when I open Strumpy Shader Editor.
First, when I open it , it popup “Save Shader Error–Cannot update shader, there are errors in the graph”. Although I click the update button ,there is just only a grey sphere on the preview screen . And the console has a lot of shader warning. Can anyone help me to fix it.
P.S. my unity version is 4.0.0f7

Strumpy no longer works in 4.x and has this bug on opened shaders
