[Koha] Amazon Questions

Hi all, I have some questions about Amazon Content. I'm working on a test dev system on Debian and have all of the Amazon preferences turned on. I have entered my associate ID and my private key as is required, but only cover images are showing for me. At first I thought it was the slash that was in my private key that was causing an issue so I had Amazon generate a new code and it too did nothing to get additional content to show. I'm up for any suggestions - maybe my system is set up funny or someone else is having the same issues as I am. Nicole
