Did you get your LimeWire from here? http://www.limewire.com/english/content/download.shtml

If not, then that might be why. I'm using the LW beta 4.11.2 & it shows on that as the attachment below shows. I can't remember but after changing language you may need to restart LW. You might also need to have that language to be supported by your computer's OS, I'm not sure.

As far as searching Chinese music goes, I find it's just as easy to use Pinyin. If you know pinyin then you can simply use the english set up.

(oops for some reason it won't upload ... I might have to redo it.)
