Broken link for material download for PsychoPy book

I am using Building Experiments in PsychoPy (2nd Edition) which points to to download materials for examples in the text.

I can go to the Sagepub website but the link is broken when I click on the “Building Experiments in PsychoPy” image. (Error message: The requested page “/psychology/resources/peirce-macaskill-building-experiments-in-psychopy” could not be found.)

Is there an active link to the material referenced in the book?
