Thank you for your post! I am sorry for any inconvenience.
We recently attempted to reach the author regarding this issue, but we did not receive a response. The website was turned off in early 2018 and we do not have any information on if it will be available again in the future.
Please let me know if you have any questions. Have a great day!
I just purchased this book and assumed it was up to date - June 2019 - as it was at Barnes and Noble booksellers. If you are selling new, outdated books, you need to either provide new content for those new purchasers (as in web content that provides the same information), update your book or put a disclaimer on the cover that the web resources in the book you are purchasing are no longer available. The reason I bought this book was to have access to the resources and that's just not right. You are duty bound to do something for those books currently in the bookstores. Can I get my money back?
