Hi,

I bought the game on amazon today and reviewers told me, that I'd receive the steam key but I didn't

Hi  JRISETH
Please go to the steam library were your game is installed the code will be there.

Nono, the problem is, that when I try to register the key on steam it says Invalid Key.

Hi
Register the key in your forum profile(not steam) this will then give you multiplayer

Note that you must register two keys.
