I've never had the problem of losing my settings on the currently installed version of LW Pro. But, I have always had the problem where the installation of the newest version wipes out the preferences I had set up. I just upgraded to version 2.7.9 and still had to re-enter all my settings via the wizard and the preferences. I'd like to see a version that does not overwrite existing preferences. Granted, it's not as bad as the problem you people experienced, but it's still mildly annoying.
