which particular morph packages are giving you problems? I have encountered one Orc morph package which does have issues when loaded; I believe the vendor might be GhostOfMacbeth, possibly RawArt. I would need to check. However, all my other 3rd party morph packages, free and purchased, do work without issues. If you do go as far as reinstalling M4, perform an initialization after each morph package, don't attempt installing the separate packages and then running initialization. It doesn't work that way, at least, that is the official word from DAZ3D. If you can provide a listing of morphs that don't work properly for you and I'll see if I have them in my collection. It will be interesting to see if they work on my system.
