They couldn't provide an answer on the "Wait for Me" show.

They helped me find the campaign; here's the map: https://www.fatalgame.com/download/maps/heroes3-map-the-first-werewolf-is-back.html I can't get it to work in the game, not in version 3, 3.5 (Wake of Gods), or Erathia. I've reinstalled many versions of the games, but it's all in vain. I get this error:
resource manager getbitmap816 could not find the bitmap8 resource hp\wb1.pcx.

Has anyone encountered this? What file is missing, and how can I fix the problem?
