I can connect to every server but a war-lords server, I have updated my nonsteam css from avia.ro and I have changed my name and config in the games directory but when I try to connect to a War-Lords server it says "Disconnect: Change your name"

I tried at first putting my name as King_Viper, I got the error, then I thought that maybe since my IP has changed, I would be saved under a different IP for stat tracking, and that you couldn't have the same name as anyone before, so I tried just King Viper and got the same error
