Gmod Engine Error

Help, When I launch Gmod the screen pops up like normal and then within a few seconds it exits out with an error message saying: “Engine Error
SteamClient()->GetISteamUser” Is There any way you can help?

Do you have a pirated version of Gmod?

Most likely.

Uninstall your Steam Crack.

No I Dont Have A Pirated Gmod!
