MartiusR: Did anybody encountered the issue with Doom 3, that the game is asking you to enter cd-key?
First time when I've launched it, everything was fine. But after I changed the resolution and closed the game, every time I'm launching it, it asks me about cd-key
I have some key entered for the second row, but the first one is empty. And it appears every time I'm launching the game, can't cancel it (game exit in this case).
P.S. To all jesters - no, it's not a pirate, I installed GOG version, received for free for owning Doom 3 BFG :)
I would expect this to be because of the multiplayer aspect of the game. You can find your serial keys in your GOG library for the game. Just choose the "Serial Keys" option from the "More" dropdown.
