You wern't banned.  There must be some mixup?  I'm looking at the logs and there's only two IP addresses coming from you.

Your 74.* IP address is similar to a cheater we banned but it isn't exact.  How sure are you that this is a ban?  When it's a ban on TeamSpeak or UT3 you'll know since it will tell you it's a ban when you try to enter.  If you were having connection problems to the server that's a different issue.  I don't do bans on the firewall unless it's someone trying to take down the machine and that's pretty rare.

And no we don't rent from UMG.
