"Normal" people don't know how to do that and UNREN anything let alone delete stuff to play the game, they shouldn't have too either.

Yes. But for most people, everything works fine. It seems that the problem occurs only if a third-party firewall is installed with custom settings. There are no issues with the default Windows firewall or with the default settings. So adding the game to the firewall exceptions should be enough, no need to unren or delete anything. I'll add a note on that to the game page and release posts.
