[Plugin: Amazon Widgets Shortcodes] product short code was working on local, not on live site

I had this plugin working fine on my local set up, when I uploaded the site to a live environment the product shortcode is no longer working.

looking at the source, I can see the <div class="awshortcode-product"> is there but no object appears inside.

I find this bug a bit weird, just dosnt make any sense to me. Why would it be find on my local then not on the live site?

I have tired re-installing this plug. I even tried installing it another live site, still didnt work there.
