dont download this version of the maphack here, 1.1.1 was detected by warden, instead go to this site:
http://www.d3scene.com/forum/starcraft-2-hacks/44508-release-undetected-valiantchaos-maphack.html
Apparantly if you used 1.1.1 during 11-10 to 11-20 then you will be banned in the near future, so get the new one!!!
