Call me retard but ... I do not understand all this, in my case I do not play online, that is ... just as I downloaded it from steam I bought the 2000 mirage and I played, I play without being logged in, basically because I do not have an account in DCS, except in the forum (I opened it only 3 days), that is, I downloaded DCS in steam, I bought the 2000 mirage and it is already, when I start the game I get the small screen to enter username and password but I always close it because I do not have an account and since I do not play multiplayer, I do not need to log in either, but that comes by default in steam.
That is to say that if now I change PC for a new one, and it gives me to play online, it will not let me log in? I wonder why I did not understand the message
