Files and options missing in my "Expression Web 4" sample files,

I bought "Microsoft Exp Web 4 Step by Step" and downloaded the sample files. I am just on Chapter 2 and two of the sample pieces are missing: 1) I don't have the Design 4/Design.exe file, 2) I only have 11 tabs in the "Page Editor Options", the "Code Snippets" tab is missing.
