Getting Error: HTTP/1.1 403 Forbidden in …inc/aws_signed_request.php

Hi there. I installed per the instructions, made sure I entered my Amazon affiliates ID, Access Key ID and my Secret Access Key but on my posts, both via shortcode AND the backend in-plugin method.

The error output on the page looks like this:

Warning: file_get_contents(https://webservices.amazon.com/onca/xml?AWSAccessKeyId=AKIAJJVCLBCAH6JQBOZA&AssociateTag=[my amazon id]&IdType=ASIN&IncludeReviewsSummary=True&ItemId=B00BEIYMTW&Operation=ItemLookup&ResponseGroup=Large&Service=AWSECommerceService&Timestamp=2013-11-15T04%3A32%3A13Z&TruncateReviewsAt=1&Version=2011-08-01&Signature=YR17sixPLety3VBw2XLWwVkqZcjvFgMZi%2Fmbx%2FbjdAw%3D) [function.file-get-contents]: failed to open stream: HTTP request failed! HTTP/1.1 403 Forbidden in [server address]/wp-content/plugins/amazon-product-in-a-post-plugin/inc/aws_signed_request.php on line 649

I’ve noticed A LOT of sites indexed on Google with this same error on their sites. Any advice?
