Console window of Acrobat Pro 2017 doesn't show any message or error.

Before, I had installed Acrobat professional 9.0, and in the console window I saw messages of built-in start script and, of course, some error if it occurred, but now I have installed Acrobat Pro 2017, and  in the console window doesn't appear anything message or error. I have select, in Javascript preference, the next options:

- Enable Acrobat JavaScript, Enable JavaScript debugger after Acrobat is restarted,  "Show consoles on errors and messages",
