Hi, I've reinstalled Chivalry and I cannot join your server as it says I'm banned.

Steam:

In Game Name:
Triptych
lol

I've been inactive for over a year so I don't know the date/time of when I noticed the ban.

Hey. It was me that banned you for racist language in April 2015, under the steam name Maverick. I'll lift the ban but please remember the rules about no intentional teamkilling or the use of the racist language in the server.

Thank you, I will follow the rules applied carefully.

Hi, I've been trying to join but it say's i'm still banned.

As far as I can see, you're no longer banned by steam ID. But you may be banned based on your IP address as well. This happens if you have a dynamic IP and your current one was banned for some reason.

The easiest way to try to fix this is by restarting your router. This should give you new IP. If you don't have dynamic IP, then MonkeyFiend or somebody else with access to the server will need to check things and fix them for you.
