Has anyone ever been able to update Mezzmo from within Mezzmo when the application notifies of an update?

On all my installs across a couple of machines it has always been the same for me. The software notifies me of the update via the dialog box but the web information is missing (just shows broken web page). Tick the update and try and install it and it just errors.

So I have to download any update from the webpage and not use the update facility from the software itself. Anyone else seeing the same? Not a major problem just wondering why it is broken and has been ever since I have used the software.
