What edition of VS is displayed at the top of the Help, About screen? Also, in the middle of that About screen is a list of installed products. If you have a web-enabled version of VS it will show "Microsoft Visual Web Developer 2005" in that list.

By the way, this isn't a good book for beginners. Do you already have some experience with ASP.NET 1.x?
