If the vocal is loaded within V4, there should be no problem even if the file is V4 itself. You should only get problems if you try and load a V4 file in the V3 vers. of the software.

Try a screenshot (note; don't use the wikia as a host).

Also consider Vocaloid Otaku forums tends to have better knowledge on this subject. Though we have just as much knowledge pool here, if not more, our focus is not in the same area as their typical member.
