My friend and I have the same version of Heroes 3 - 4.0.0.0. We want to play over a network using Hamachi.
He creates a map, I connect to him via TCP/IP, and everything seems to be working fine. But then this happens: He takes his turn, passes the turn to me, and when I finish my turn, a blue bar appears with the inscription "sending data 86%", and everything freezes. After a while, "Data transfer error. Try again?" appears. Retrying doesn't help.
What could be the problem?
