The past few updates the affinity products have notified me of have led to 404 pages and I've just worked out why: I use the HTTPS Everywhere extension, which tries to force http requests to https. When disabling the 'encrypt all sites eligible' option in the extension and changing the url back to http, the update link will correctly redirect to the download page for the updated software. I'd appreciate a fix for this issue so I don't have to manually disable the extension and correct/reload the url every time a patch is available. While this is an issue affecting the serif site moreso than the desktop products themselves, it affects the links presented within the products when prompted to download updates.
