I saw my specific problem in another area, but not the Tacview section so I will post the question here. I am using 1.6.0, registered, and cannot seem to get anything saved from DCS. When I go to the tacview folder after the mission, I see the mission name, but only 1kb recorded. What did I do wrong? These were MP missions, and the Host did record, and had all the required areas open in DCS for data to transfer. I get the same in Single player.
