When downloading using the Quickmap Data Download Manager, you may get this error:

Downloads are not available

This can be for a number of reasons, but most likely because you are set up to receive your updates via the HTTP protocol, but you are using the old Quickmap Data Download Manager which only supports BITS and WCF protocols.

To fix this, either contact Quickmap to use an old protocol or (preferably) update to the latest version of the Quickmap Data Download Manager.
