As a google search of Heeks or Heekscad doesn't bring up my paid for domain name "www.heeks.net", I decided to cancel it. All it did was link directly to my google sites website https://sites.google.com/site/heekscad/
Unfortunately I realised after, that I link to it from my HeeksCNC software, which many people have downloaded, for the Help links from dialog boxes and from the "Online Help" menu item.
If you want these help items to work, simply download the latest trial software from my website https://sites.google.com/site/heekscad/
If you have the full version of HeeksCNC, please send me an email and I'll send you a link to the latest HeeksCNC 1.3, so you can download it.
