We've posted this to our FAQ section. Wiley had to remove all code downloads for books that we did not purchase about 2 weeks ago. We were determined to keep everything there until we were asked to remove it, and that day arrived. Apress.com should have what you need. I've heard some people say that their code is not there and if that is the case, then you need to contact Apress's customer service to see about getting it.
Sorry for the inconvenience,
Wiley Publishing/Wrox Press
