Did you set the hunting area ??
If you dont see the hunting area tab, click views -> hunting area
[Only registered and activated users can see links. Click Here To Register...]
click current position -> change radius from 200 to 70 -> click add hunting
** after clicking current position, make sure the x and y co-ordinates reflect your characters co-ordinates correctly (confirm by co-ordinates shown in top right hand corner of game)
Then go to the bot tab and click start bot
{edit} Oh yeah, and if there is already a co-ordinate in the box at right, make sure you remove it before you add your current position
