i've also the same problem. why does my installs only in chinese? but i've it installed before in english. i've used and played it before already. im using the same cd installer. but i needed to reinstall it because i formatted my system. but unfortunately it installs in chinese. i've tried it already several times but still its in chinese. what's wrong i browse the cd but i couldn't found on how to change the language.
Maybe because they don't have a Philipino version. Change your Windows unicode(location) to United States, then reinstall, if that doesn't work, I don't know what to tell you.
