The S3 access credentials are invalid

After updating to the newest version of the module I am now receiving the error message on the admin/config/media/amazons3 page that says "The S3 access credentials are invalid". I am using the correct and newest dev versions of the modules: Video, AWS SDK for PHP, and Libraries to handle video on my site but this has error is not allowing the files to be uploaded to my S3 account. This in not a local MAMP or WAMP environment and ws working fine before the updates. Any idea what is happening? Any help would be appreciated.
