Glad you found it because I replied to the mail I got about this post without realising it was a forum topic :S, just got the bounce message.
There is a forum topic as well talking about the move of the assets, especially since the host’s were so nice to close their site BEFORE they moved the tutorial and assets :D. their page or my backup (or in the code download that accompanies the book :P)
Here was my mail 😀
Glad you are liking the book.
The Win 8 platform starter kit assets site got moved a while ago, and
they nicely just took the site down while they did it.
So I've put the assets on another free download.
It was listed in the forum for the book (which was listed in the Code
Download section for the title)

Let me know if you have any further issues.
