How to play Heroes of Might and Magic III online via Hamachi?

We gathered to play with four people!! We downloaded all the new versions of Hamachi!! No one could connect until we reinstalled the old versions!! I still don't understand what the problem is??? Any ideas???

You know, I'm even hesitant to answer, because in my case, the people I couldn't play with in the previous version can now connect without any issues. There aren't many possible solutions, and the main one is that you were just unlucky, or Hamachi's server had a restart.
