B4R Question dont run log() command

Hi all of you.
I have a very simple problem.
I use log("hello") command in my B4R project but do not show any text when run that.

Another thing, try to reset the board after the program runs. I have a device that only starts logging after a reset.
I reset arduino board and didnot currect.
this problem evented when I installed new version of B4R.

i think this problen never be solve. I must use LCD for view log.
