UTAU can't locate .wav files in VB folder

[Masa]

I personally don't have this problem, but several people who have downloaded my VB had the same problem! But it worked for other people, I also tested it, and everything's fine, so it's definitely not the file that's the problem.
What they said to me was quite confusing, but here are some screenshots they sent me:

^ Notice how it says "File: 0, Size: 0bytes"

If they try to add the VB in Option, the browse pop-up thingy doesn't show any .wav files:

But if they change it to All Files then the .wav files show up:

I asked them if they've set their locale to Japanese, and one person was very sure that her locale IS set in Japanese.
Also, this is different from the problems I had before I changed my locale. Back then, none of these happened, everything loaded properly, but just wouldn't play.

Does anyone here know what the problem could be?

Looks an awful lot like her computer isn't in locale, to me. If it is, UTAU hasn't noticed, that's for sure.
Tell them to triple check that their locale is Japanese, then uninstall and reinstall the program. It's their computer, not your bank.

ask them what OS they're running and literally google "change locale windows (their OS)" Give that to them.

because people tell me "my locale is in japanese yes it is IT IS."
then I make them change it and they say "oh. uh. yeah. it wasn't."
