Best to pm me the ip address you are connecting to the server from .. ie whatismyip.com
I do not see either your names or known ip's as being banned by anyone...
If you are having trouble connecting to the server and not actually getting any response... then rest assured I have the same problem at times... You just gotta try again later.
Nothing I can do about fixing it unfortunately, you and your friend are not banned anyway.. I would have given a reason for it and you would be able to tell me what that was.
