When you unistalled V4 did you look into every nook and cranny in your runtimes? A lot of times bits are left behind like old data. You have to make sure that everything is gone. 

Are you using old installers for V4, zips from Dim, or zips downloaded from Daz?

When you re-installed the morphs++ if there were hidden bits left behind the data could be corrupted. Did you re-intialize V4 after you reinstalled morphs++?
