Please note that this game is NOT part of the Deus Ex series. Not related to it in any way. It's a weird arty piece of gaming history. You don't play it, you look at it and listen to it. If that doesn't interest you, it's probably not going to work for you, in a big way.

Once upon a time, a game key was a sacred thing: you bought it, you owned it. Not any more, alas. Keys get revoked these days for no reasons in the world.

This key is an old one. I keep track of these things as best I can, and my records say I haven't used it and I haven't given it away, so it should be as valid as the day I bought it. If it isn't, please let me know and I'll check to make sure there wasn't any mistake on my end. If I can fix the issue, I certainly will.
