If you have the installer, just use that. If not, go back to your bookmarked pro page: you can just get it from there. If you don't have the page bookmarked, the pro support page allows you to find it. You don't have to pay again. btw, the uninstaller doesn't remove the prefs--search for anything "lime" to find those.
