, that SERIAL:NOT AVAILABLE confuse me a little soo i start search for serial or something, but I can't find any. Do that mean i got illegal coppy or what?
Edit. I CAN play this game via steam, there is no problem with launch game, I just wanted to register game on matrixgame but I need serial number, but i don't have any, is that normal?

Sorry, I had things backward. If you buy the game on Matrix and then register, you get a Steam key. If you buy on Steam, you can register with Matrix as you did, but there is no key.
