The Card Shark (Demo) download link for Offline Installers is not working for me, either via the browser link (goes to an error page) or via the SDK where the manifest cannot be retrieved for that game.

Thanks, though I was able to use another program at the time, to get the Windows file download.

Checking that now, it seems the MAC download was and still is the issue for obtaining the manifest entry for the game, so that obviously hasn't been fixed, as trying to get the manifest just now, still fails.
