Query: The vb version of this book has missing or corrupted mdf/ldf

I have the c# version of this book too as I amlearning vb.net and c#The vb version of this book has a corrupted database fileand other 2 missing database files.That makes 3 chapters which you wonder if the code is going toever work in this beginner bookFor a book from Karli Watson after his brilliant book'begining c#', his reputation for quality is not going tohold water for people making his purchase. Certainlyafter anyone spending money on this vb.net or c# versionof this book finds out that they are tryingto sell you a book with questions with no answersI see other people can give the book 5 stars withouttesting the downloadables. Don't make any sense.
