Not sure why this is happening other than maybe its on a non-coop version ? Make sure also you didn't join from another server possibly. Let me know if it happens again and to multiple people.

It's happening right now. The map is on Heigth, and I can't join. The error is "Disconnected" then below the path to your theatre, and below a greyd out Cancel button, an an actie Ok button. That's it.

Oh, and, the path to the theatre is not correct, it points toward insurgency\scripts\theaters

Ok, actually it's not related to heigths. ame problem with a different map after a reboot. I guess it's linked to the last update.
