Wondering if someone could help – would really like to use this

Have installed this plugin and all my upload files are in my Rackspace files container. The plugin is configured correctly as far as I can tell and the sync is complete according to the plugin. However none of my images are appearing in the site although new media does appear to be uploading to my files container. Even on the admin side of my site uploaded file thumbs are not appearing and everything still seems to be referring to /wp-content/uploads/. What am I doing wrong?
