One, do you have use external binary morph targets unchecked in your general prefs?

If not, uncheck it.  Load V4 into the viewport and resave the figure to the figures library.

You may need to re-initialize V4 by running the bat file in the !DAZ folder that resides inside the libraries folder.

These things ususally fix the problem.  Make sure the Morphs++ have actually been loaded.  Sometimes you need to reload them to get them to work.

Remember that V4 has a ton of magnets attached to the figure and these can wreak havoc.

 

No, you have to have at least one light loaded in order to see what you are doing.  The cameras are cameras, not light sources.
