I pressed the quit button and the program Final Cut Pro won't shut down. Please help!

Hi,

I tried to quit the program Final Cut Pro X and as usual, the loading message "Quit Final Cut Pro: Annulation des tâches d'arrière plan..." pop on my screen. But, the message won't disappear and the program is still open. I tried to restart and shut down my computer and I always have the same message: "Impossible to quit. Final Cut Pro is opened".

Please help,

Thank you,

Jeremy ***
