Me and a few of my friends were playing Arma 2 over hamachi, and as a joke I thought I would kick one of them. However, I accidentally clicked "Ban" and he was shot off the server. I have tried the "#exec unban xxxxxxx" command with both his player name and id both in the lobby AND in game. There is apparently supposed to be a bans.txt in my appdata/local/Arma 2 folder, but that was not there either. I am running the latest beta patch and I have googled and tried every solution to this problem, and none of them worked.
