Right. I join a server. It doesn’t even get to the file downloading step without it saying:
"Account Used Elsewhere
This Steam account has been used to log in from another computer. To continue using Steam, you need to log in again."
No one else is on my steam account (that I know of :ohdear:) and getting into TF2 servers is fine. Could one of my add-on’s be causing this? I would like to know ASAP because playing singleplayer isn’t as fun.
