Kigen's Anti-Cheat

I apologize, they sorted it out and apparently i was not banned by KAC. Thanks for your attention anyway.

Today i noticed i was banned from one of my fav TF2 servers. They think it could have been the KAC system. Could you please check my ID and tell me if it was banned by this system? I have never cheated a day in my life. The only thing i can see weird happening is my Steam client seems to update itse...
