First, this isn't the board to ask for help with the game, but a meta board for the site itself. The thread you're looking for is >>>/yn/513
But I'll answer your questions anyway.
You aren't supposed to just install Applocale, but also to run it (and YN through it). If the game still crashes, we can check what went wrong again, once it's all done. How do I know you aren't running Applocale? The error should be in japanese instead of showing mojibake.
Even so, I can predict what the error is saying already. Your YN installation is missing a file; I can't remember if it's a background or a system file, or the title. But it's one of those anyway.
Did you download the game from this site? If I recall correctly, our version should be translated and it was free of these missing files.
