For what it's worth I had some problems with the ASP Project in Chapter 14 also. After wasting a lot of time trying to debug and find the problem I finally was able to communicate with the author who sent me the latest version of the code. It works as advertised in this version. It appears he didn't upload the working version.
I have posted the version the author sent to me. It's on my website at "WebTutor.cc" Follow the download link to the C# download page. It is a self-extracting zip file.
Hope this helps.
