thanks frago for info. just use the tcadmin panel to reach the admin tools (origins guard 0.5). if you don't know how to create an account, read the faq on http://lagfreeservers.com/ . log in, press ban list, then my custom ban list. unban the guid u want to over there. then go back to tcadmin panel, use the update ban list tool. then go to rcon console tool and reload bans. that's it! kind regards wong. p.s.: if your ban is not in there, go to tcadmin panel, configuration files, bans.txt. search in there for the guid and the ip, delete them. then reload bans in rcon tool et voilà, it works.
