because Amazon changed their API (see the Announcement at developer.amazonwebservices.com/connect/ann.jspa?annID=476
) the Component isn't working anymore since a few hours.
Could you provide a patch for existing installs? At the URL above is a description what they changed (now only Signed Requests are accepted).
I generated at aws-portal.amazon.com a Secret Access Key and created a new Certificate File. But the component gives this error (when trying to add a new media)
SOAP Fault: (faultcode: aws:Client.MissingParameter, faultstring: The request must contain the parameter Signature.)
