I see that Sexy Shapes 4 relies on the V4 Morph++ package which explains why it is not working according to your post.  Do make sure that the Morph++ package is installed into the same runtime as your base V4.  Also reinitialize whenever a new morph pack is installed.  Load a new V4 from the basic folder and attempt to apply the morph++ again.  If you are using a saved V4 model prior to installing Morph++, that figure will not have the necessary channels create to accept the INJ Morph++.
