I got a message while connecting my my L4D server "Invalid protocol, expecting 1038, got 1031"
This is because the game hasn't been updated. I haven't been able to connect to my server ever, customer service is dodging me, and I really want compensation. This server has never worked and it's on a fresh install. It seems like the L4D 1 servers have been abandoned on this website. I can't install my own updater since you won't allow .exe files, which is a huge pain by the way and not normal.
