Hi,

I've got similar problem - I bought that program a couple of years ago. Now I've upgraded my computer, and the icon for DMM is left empty. I tried to download from the same site you tried, with no effect - there is no contact for them or any place to put my serial number in. The site advised on Forum does not work at all, nor does Sienzo.com, and there are no contact details in the manual...SOS! Did you manage to contact them eventually?
