MinimWatch won't launch

[lyapounov]

Hello !

I had the icon minimwatch on my mac; worked perfectly. Then I closed the app; and now I can't launch it again - meaning no icon in the task bar.

Then , after many attempt, I have an pop up window which says (translated from French) :
"Impossible to open application MinimWatch.app because it does not answer."

I am under Mac Osx 10.11.5

Where is the log file, so I can see what happens ?

Thx !!!

Best
