Cubace IC PRO cannot connect


I use :

  • Cubase IC PRO on Ipad 3 and IOS 7.1.1
  • Cubase Elements 7.0.7 on Windows 7 64 bits
  • SKI version is
    Since installation, it worked perfectly.

But now, Cubase IC PRO cannot connect, even if i specify the IP address instead of name.
My Symantec firewall is open.

I have reinstalled SKI on PC.

What happens ?

Cubase IC PRO can connect from my iPhone 4 / IOS 7.1.1

After restarting WIFI on my LiveBox, it works.
