I purchased the book and tried the steps given here. It fails for me; it shows an annoying captcha, then either gives me *another* captcha (which, I assume, means I didn't read the previous captcha correctly) or gives me a 404 error ("The requested URL ... was not found on this server.")

Later: Ok, I got it to work by using Firefox on Mac OS X. (The UI isn't as described here, but it can be figured out.)

Not aimed at you, but: Mr Saunders, *please* consider not punishing your customers this much!
