Try please if it work when you disable your Anti Virus for 15 Minutes.
@Madness: thats normal if you try to run Tibia without BOT, The bot asking to setup the Port to the Cipsoft Server and if you run it manually (without the Bot) it dont have the Port so it can't find the Cipsoft Server.
Strange issues here, if you want i can take a look on it when iam at home onTeamviewer or Skype.
