Okay, so that`s not exactly what the popup dialouge error box says (I don`t have japanese locale on my music-mixing computer, so it comes up as a bunch of symbols) but that`s what it said when I tried running Vocaloid 1, too, and both took me to the same thing, so I imagine that`s what it says.
Anyway, I just got Piko today (early christmas gift ;w
and I went to open the editor, and I got this error, which then took me to some audio settings (Synthesis engine, Output, Wave File output) but no matter what combination of settings I use, when I hit okay, I get another error (Again in symbols) and then it all just closes, and the program doesn`t open.
EDIT: If it makes a difference, I`m trying to run Vocaloid2 on Windows XP
