For WED I had to click File->Preferences and then on the Options tab click View Options. After this I had to scroll down to bring the Video Out textbox into view and click the folder icon to the right of it. From there I was able to do the same thing I did in MED... switch the GXL Object dll for both the 2-d and 3-d views from Gxl2BasDx9B.dll to Gxl2BasDx9a.dll by unchecking the former and checking the latter. After this I clicked OK, Apply, OK and the grid lines appeared and I was able to add new objects.
