I can't open my server for some reason

For some reason, i can’t open my server. I oppening my starting file, and an error showing up, that says
“the system cannot find the specified path. Press any key to continue”. I tried to open my FXServer, But it always says, that is unable to load configuration file:

It says to check ‘D:/Server/txData/default/config.json’ . I checked it, and i can’t find “config.json” file
Maybe there is an option to get it…?
I’m not very knowledgeable about these things, so it’s hard for me to pinpoint the problem.

same here any fix?
