'Let's play Heroes 5 online.'

I'm asking for help. Heroes of Might and Magic V - Tribes of the East 3.1. Playing through Hamachi. When creating a game, it's not visible. I tried creating the game, and my friend tried too. We also created rooms in Hamachi. I read the entire thread, but none of the above helped. Hamachi has the highest priority in network settings. Windows 7.
