Google Docs Embedder won’t show my document

Hi there,
I have installed GDE and have pasted the following shortcode into my site.

[gview file=”https://www.sharespeak.co.uk/wp-content/uploads/2010/05/InsightMay2010lowres110510.pdf”%5D

It tells me it can’t retrieve the document?
The file is on my server in the uploads folder which is public and I uploaded the PDF through WP itself.
Any ideas?
Ross ??
