I always think that gog sell game that work on modern PC... i buy this game cos nostalgia. But today i try install it and play campaign and... NOTHING happen.. it will open main screen and after that.. puff.. program not working.. GOG any solution?

Do you have DirectX 9.0c installed? Do you tried running the game in compatibility mode? Do you use OpenJK? If yes, try running without that, if not try putting that mod in.

For first this is what I try if a game crash for me. But you can help others understanding the problem better if you share your PC's specification.

Sorry, but I don't prove this.
Game perfectly works on my Windows XP, 7 and 10 machines. Right now I'm testing my own translation for the story modofication for JA.
