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
