This is most likely a problem with your Amazon account which is not approved for the Product Advertisement API. Please refer to my blogpost: http://www.wp-amazon-plugin.com/2012/682/issue-with-using-the-amazon-products-advertising-api-for-associates-request-from-blacklist_xyz-is-throttled/
You should contact Amazon to activate your Account for the Product Advertisement API.
