Technical issues with Heroes III.

2. After installing the HD mod by javdet.

What? :eek:
Thank you, of course, it's a great honor, but unfortunately, I am not the author of the mod...

Regarding Hamachi, there was a similar problem a couple of years ago. And as time went on, more and more people in Hamachi appeared with whom I couldn't connect. There were two versions. The first is that my provider has a specific protocol that "doesn't get along" with the protocols of other providers. The second is viruses or a corrupted Windows installation. It turned out to be the latter. Reinstalling Windows solved all the problems.
