We have identified a problem with using Quickcast from FTP in that files are being placed in the Drop Box instead of being automatically cast. We are working to resolve this problem.
In the meantime, files uploaded via the Drop Box or via Quickcast can be published out of the Drop Box successfully.
An update will be posted when this is resolved.
UPDATE: This issue should now be rectified. Please contact email@example.com with any questions or concerns.
