Even if you both are currently getting errors, I think it's far too early to call this a collapse. I have a lot of experience with Japanese software and Japanese developers.. I am not trying to be discriminatory (I love the Japanese), but Japanese software, especially in terms of UI, is generally trash. It never functions properly and it's always a mess... A mess in the coding and a mess in the UI. I would not be surprised if this is just a bug caused by incompetent developer(s).
