Even though the game is in English, you might have to set your computer language to Japanese for it to run.
You do this in Windows 7/8 by going to Control Panel -> Language and Region -> Change Location -> The Administrative Tab, and set System Locale to Japanese. Then reboot.
After you play the game go to the same spot, put it back to your country of origin (United States if you’re in the US) and you’re back to normal.
In my experience the game won’t play without doing this.
