I had issues setting this Up I used the community forum and wasn't too impressed by the response. As I had paid for the plugin I submited a support ticket, The support person was stunning and I was up and running within 24 hours of my request going in. Not bad for a $29 plugin. Highly recommend with Amazon S3 and Cloudfront.
1. Pitfall I faced was "Error access denied" in my cron Job. MY Hosting restricted this function on shared hosting accounts.
