I am new to the bot as well, but if you search through the forums you can find a lot of information. That being said, once the bot is up and running (ready) it needs a profile. If you do not have any profiles create a blank .xml file with <Profile/> as the entry and name it combatbot.xml, and then hit start. Now you play TOR as you normally would, but now the bot will do the Combat Rotation for you.
