Amazon widget not working

Not sure why but my Amazon widget (link to my book on Amazon) has disappeared.
I think it may have something to do with updating the version of WP.
Contacted Amazon, thinking it’s them … but it’s not. Have gotten the HTML text and dropped it in again … but still no show.

In case it will help, here’s code:
