Shader debbuging by VisualStudio

I'd like to debug my shader by Visual Studio2013 Professional.
I've followed this guide: DebuggingD3D11ShadersWithVS.
But, I can't start.(I don't see “Use ‘Print Screen’ key to capture a frame” message in top left corner of the application.)

The following message appears: "No symbol information"" ”Debug information is missing or does not match. I can not open the PDB file or I can not find the file.”
