Alternatively if you have a clean 1.4b install ready (which you can create by removing all mods you installed with JSGME) , create a new folder (like SH3GWX for instance), copy the whole content of SH3 folder inside. Get a little program called MultiSH3 - available for download at UBRS - , put it in the new folder. When you run it, you create a new folder in "My Documents" (I named mine GWX), apply GWX to the new install, enable optional mods with JSGME and off you go.
No need for reinstall from DVD.
