Sharing courses with AWS: Issues with CloudBerry?

Hi everyone, I've been reading previous threads re: sharing courses through AWS. I've followed the directions for using CloudBerry; however, I've hit a snag and am curious if anyone else has experienced the same thing. 

When I go to create a "bucket" on the right-hand side of the CloudBerry page, it tells me that's a feature available only for a commercial license, which looks like it costs ~$40. Am I doing something wrong, or do I indeed need to purchase a commercial license for CloudBerry in order to host and share courses via AWS? 

Any help/guidance is much appreciated.
