Having gone the route of deleting the keycode file and re-entering in order to get out of the endless "Autoupdate loop," I am now experiencing that double-clicking on document icons, although launching the associated Office app (e.g. double-clicking a Word doc icon runs Word), does not actually load the document. You either have to go through the Open pull-down menu or drag and drop the document icon into the new document window. I see others are reporting the same problem over at http://www.macfixit.com/ Has MS acknowledged this problem? Anybody come up with a fix other than the obvious workarounds noted? Minor, perhaps, but an annoyance all the same.
