Youtube dispute

I uploaded to youtube a video with a music track from Envato, and I have received a copyright claim notification. So I started a dipute and attached a license for the music track which I downloaded from Envato. Now 9 days have came butthe dispute is still under consideration - http://joxi.ru/ZrJlWxRHMR9pM2

The question is how long should I wait for the copyright claim disappear?
