WIN_IMPROPER_QUIT_TITLE error?

[Busterking]

I'm getting this box popping up when trying to start my dedicated server:

WIN_IMPROPER_QUIT_TITLE

and in the box it says:

WIN_IMPROPER_QUIT_BODY


Anyone can help about this error?

Problem solved:

The localization.txt file was located in the main folder, moved it out and server working.
