Hey all! I'm the original author of this plugin and, as you can see, I basically discontinued development on it in favor of a different plugin. That plugin used to require payment, but now there is an equivalent "free" version of the plugin here in the repository that you can download: http://wordpress.org/plugins/easyazon/
EasyAzon is a much better fit with the WordPress UX at this point in time and will be supported for the foreseeable future. If you're still using Amazon Reloaded, please take a look at EasyAzon and use it instead. Thanks!
