Why can't I open a server?

[J.Komando]

give this error: Failed to create key: Your account has not verified ownership for this game
I follow all the steps but no result.
Can't regular players open a server anymore?

You need to verify that you own the game you are trying to host.

Xerxes I can't verify that I own the game. Can you tell me how to verify? Because even though I tried to verify via forum plutonium and the game program, I got an error.

J.Komando do you actually own Modern Warfare 3 (2011) on Steam?
Not the dedicated but the actual game

[J.Komando]

Resxt Ah No, I only have the free version. I have to buy the paid mw3 to open a server, right? I thought it was opened with a free dedicated server.

J.Komando you need to own the game you want to host to host it yeah

[J.Komando]

Resxt Now I understand. Thank you very much for your interest.
