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

I downloaded Hamachi, and it displays some kind of error message during setup. It says that the firewall is blocking the port. Although, I actually disabled the firewall. Can you tell me what this is? It seems the firewall is still running. Are you absolutely sure that the Windows firewall is disabled, and that you don't have another one installed? If the Windows firewall is enabled, do the following: Start -> Settings -> Control Panel -> Windows Firewall -> click the second tab, Exceptions -> Add a program -> select Hamachi and click OK -> click Apply. P.S. You must have administrator privileges.(c) Geksorin
