Anybody who can read Japanese know what this warning means? I followed the install instructions but got version 1.11 instead of 1.21 somehow.
Why didn't you just run it through google translate or something ( Ctrl + C copies text from all message-boxes in Windows )? System errors are pretty clear and easy to have translated.
OCR'ed and then did that, to which the error states:
"Failed to save system data. System files may be in use by other programs. Please save the data again after waiting for a while".
Common cause for this error is 1: HDD failure ( partition is causing corruption of whatevere files are being saved, making it look like it's in use ), 2: Lack of permissions ( i.e; it's trying to save the system files in a folder\partition that requires an elevated permission that you don't have, i.e; need to run it as admin ), or 3: It's actually what it says. The files are being used by another process and therefore can't be altered.

As for version. Version 1.11 is the translation version, not the game version ( translation team decided to overwrite the version numbers themselves and use their own, rather than keeping the original, or doing both ).
