What does the error says? With this information I have no idea of what it could be
What I can think of is that you may not be using the japanese "uncompress name code" (I am not sure how it is named on english) called "932 ANSI/OEM" . What you have to do is open the zip file with winrar, go to options, name cifrade and change it to the japanese one (932 ANSI/OEM), after that, uncompress and you should have it. I notice this because the music files had a weird simbol name instead of a japanese one. I hope this helps.
