Ok for starters Im new here my name is Matt I live in the USA State:CA but I have a very popular question how the hell do you get rid of that damn error that comes up when you try to play online with Garry's mod that says Disconnect:This Steam Account does not own this game?
Please if someone could help I would be very thankful
