Am posting in frustration as my question about HoMM3 has been derailed.
No, you derailed the thread with your HoMM3 question. This isn't a thread for tech help -- you can find that in game forums as stated. You may have to be patient.
Unfortunately GOG support isn't the most responsive, at least lately. Though they do seem to have technical issues on that front, so perhaps they simply didn't receive your mail. You could try directing them to your thread via Twitter as they seem fairly responsive there.
