The game is saying my steam id is invalid for some reason, and I don't know why.
When I open the game it brings me to this page, none of the people are animated, and then states that I don't have a valid authentication ticket when I try to log in. I did all the steps in the error procedure, and nothing had changed. I always open the game from the Steam library, so it wouldn't make a difference if I didn't. Since this is my first post on a forum, I have no clue how to post images, and it looks like they are disabled. If it helps I am currently on a macOS, System version 10.3.6. I do have screenshots if needed, just got to figure out how to post them. Any help would be appreciated, I've been playing this game for years and would hate to lose my account.
