Try updating Vocaloid (see our Vocaloid3 page). If that fails, you can try the classic "re-install them in release order".

This shouldn't be so with Vocaloid3 though, so I'm buffled as to whats going on here.

But if neither of these two suggestions work your going to have to go to vocaloid otaku forums for help and suggestions as these companies don't naturally have English support offered... Because you know... Not English... :-/
