Hmm is that all the log says? If so, make sure you have everything setup properly, e.g. turn off resized mode (enable fixed mode), start script while logged in (if any problems)
otherwise, just paste the entire log
Unlucky if it was a 2 day ban then you must've got sniped by a jmod, make sure to speak every once in a while, or join a clan chat and babysit the bot if you are worried.
Just as I assumed, you are using resized mode - please make sure to use fixed mode otherwise NO bots will work whatsoever. Simply click the left monitor in the RS settings tab and it will become fixed mode
