Either using Applocale or setting your system's non-Unicode whatever to Japanese, that's what.
some other kind soul will explain how to do it or you could just check the archive as well
That's weird, I tried doing that, it didn't work… :cc
probably a corrupt file. What version are you using? if you have the orignal zips/rar's re install it, it should fix it's self.
I'm using version 94. I'm not sure what counts as the original files. *stupid*
