I couldn't download the campaigns from the link on artifactheroes.com (maybe I'm just not very good at it).

Don't worry, your skills are fine! :) It's just that artifactheroes.com is hosted on a paid hosting service, and when the website authors didn't pay on time, the hosting provider simply disabled the site and showed various advertising links with similar words instead (contextual advertising).
I have "In Search of the Sword" (although I haven't played it myself yet, but I'll try to sometime).
When so many people rave about someone's campaigns, it means they are really very good!
