Me and my friend bought the NA usa version online with paypal. Both of our region are in Canada I can use option---> account---> language and change it to chinese traditional no problem. (and download an additional 2.7gb file) But he can't. We both use Diablo-III-8370-enUS-Installer . Any idea how to? His game client don't have option to change to any language, it is locked in English. He's currently in China, if that has anything to do with it?

thx alot
