I'm not really sure whats wrong. I changed the system localization to Japanese, but when I open the application, an error message pops up and then all I can see is white and some text at the top. All I can do is open and change the settings; and I can also see the option to go to the title, but it doesnt take me o the title, and no other options seem to work. I tried re-downloading it to see if maybe it was that I didn't download it right or something, but the same problems keep happening
