At the download option page
http://www.limewire.com/english/content/download.shtml, we have to choose the OS, which are ..... Windows (English Only), Windows, Mac OSX, Mac Classic, Linux, Other.
I first chose "Windows (English Only)" to install LW English version but somehow got the Chinese version. This download page doesn't show the language options.
Later, I uninstalled and changed to click the OS "Windows" and asked me to choose the language (English or Chinese). I finally got the English version here.
I guess the first installation problem occured because LW detected my OS is Windows Chinese version instead of English and LW transferred the Chinese version to me.
Case closed ... haha.
