'Let's play Heroes 5 online.'

Gentlemen, please help in any way you can. The problem is: We decided to play with a friend over a local network because Ubi is glitching and lagging. Since it's impossible to connect directly, we decided to use Hamachi. We connected, created a network in Hamachi, both of us logged in, we can see each other, and the ping is normal... But in the game, over the local network, the heroes don't see us at all. The player list is completely empty. Those who play Heroes over Hamachi, please tell me what to do? The Heroes version is Tribes of the East, a licensed copy.
