Robert, I had a brief discuss with Wes (author of this manual) and he is working on upgrading the manual for latest version of SolidWorks. You may check this thread and ask the people who recently bought it : https://forum.solidworks.com/message/317167#317167

I decided to go ahead and buy the routing manual since the sight lets you download it for a year. I recieved my paypal confirmation immediately and got my login info within 6 hours of purchasing. I can't wait to start routing!
Wes put this at the bottom of the email...
Just a note: I have been working diligently on the 2013 version, and hope to have it uploaded to the site in just a few weeks.
