Heroes 2 online. Applications. Issues.

Well, what can I say? If the game simply crashes without any apparent reason, it indicates a critical error. There aren't many versions, and older programs are very sensitive to data transfer over the network. I would advise you to buy a licensed copy of "Heroes of Might and Magic" from Ubisoft – the so-called "Platinum Edition." It comes without a disc, and you can install it for yourself and your friend, and then you can play together. There shouldn't be any errors. If you're trying to save money but have internet access, download the latest patches; they might fix the error.
