The output suggests that you are using an older version because the KPOINTS section is not recognized (assuming the section was placed in the correct subsection i.e. FORCE_EVAL&DFT). Your input will only work using the trunk version of CP2K (the section related to band_structure printing has been moved since version 4.1.).
