After install the certificate I bought from a Chinese reseller, Directory Opus automatically changed the language setting to simplified Chinese. How can I change it back to English?
I Tried:
- 
Change it in setting. But there are only two options available, simplified Chinese, or traditional Chinese. Then I googled about this problem and tried another solution in this thread: 
- 
Fully exit Opus and change it via command line "C:\Program Files\GPSoftware\Directory Opus\dopus.exe" language=englishand also failed, it first shows Converting configuration to new language. Please wait...
  but then 请稍等…正在应用新语言…, change it back to Chinese
