Dear Vladimir,
I did not find your book at Apress either. Wiley did not purchase this book and we can no longer distribute the code we received for books that we did not buy from Wrox's liquidation. Though I'm not sure if errata would have been part of those files anyway.

I had been under the impression that Apress purchased all remaining books so I am not sure why this book is not in their catalog. Did you try contacting their customer service? Their site has [email protected] as the email for them.
