I own MX also, NOF says they cannot give me the file, which is keeping me from upgrading cause they worked fine for me, and I bought like 4 licenses already though upgrades, they are kind of making me upset that I cannot download an older version, it seems like a force to buy a new version when I do not need to. Not right, over the years we quit using it now we are back with needing to make websites and the files we had are corrupt or gone..
