Please describe what you did and what went wrong with the calculation in detail.

1) The script appears to use old ATK Python commands that no longer exist. The script was clearly not made using the Script Generator using a recent VNL-ATK release.
2) Your structure is not periodic along any unit cell vectors, but your calculator uses k-point sampling, and you are asking about the electronic band structure, which only exists for periodic structures.
