If there are problems still in Safe Mode, then no, nothing you could do
(Word Data key or anything else) would be likely to help. Is there somewhere
that you could post a screen shot of what you're seeing? For example, with
the Ribbon minimized, I see a title bar at the top and then something looks
like the old-fashioned Menu Bar that says Home Insert Page Layout References
Mailings Review View, etc. and then my QAT below it and the ruler below
that. If I click on Home or Insert or whatever, that tab will open
temporarily. Or I can right-click on the "menu bar" (which is really the
tabs of the Ribbon and click on "Minimize the Ribbon" (to deselect it), the
Ribbon reappears. The same if I double-click on any of the tabs.
At the bottom of the screen, I see the status bar, with the five View
buttons in a row, Print Layout, Full Screen Reading, and so on down to
Draft. In Draft view the entire screen is white; in Print Layout view there
is a white page with blue on either side. If I have the Zoom increased to
(in my case) 170%, then I still see white all the way across (but of course
the text would be gigantic). I'd still see my margins because I have text
boundaries enabled, which I imagine you don't.
