WiDi doesn't work on my Asus UX31A since Windows 8 upgrade

Notebook: Asus UX31A

Adaptor: Belkin Screencast

OS: Windows 8 Pro

Hi,

My Widi used to work perfectly on Windows 7. Since I have installed Windows 8, after having installed all the drivers for Win 8, i can't make my Widi working.

The Widi app show me my adaptor Belkin Screencast in the list but when I am triyng to connect it, I have the message "Unable to connect to distant display (My message is in french so the translation can be different... "Impossible de connecter à l'affichage distant").

I tried to re-install drivers of Wifi / HD graphics and the Widi software.... I verified the firewall..

Can you help me ?

Thanks
