Finally I found the solution!
I have checked everything as per instructions given on Steinberg site (link provided by Oliver):
- Bonjour service is running
- Cubase is activated in Windows Firewall (both private and public networks)
- I have set up a new ad-hoc network with WEP security. Previously my ad-hoc network don’t have any security and now it is a problem!
So, to conclude, check your ad-hoc network, since for previous version of iC pro security option is not needed.
Now everything works fine and smooth.
