To Aqua

I am probably writing this to you too late as you have probably already found this out, but, if you are having a problem running the game getting a message in japanese like "missing register" you have to run the file "ioregadd.bat" after which when you click the "io_r2_en.exe" again to run the game it will now launch. If this wasn't your problem please forgive my unsolicited advice.
