WotLK Client for Mac Not Working

Hello, I'm new here and need some help.

I just downloaded WotLK on my Mac from the warmane.com website and it's not working.
When I first opened the game (not the launcher), an error read "The application "World of Warcraft" can't be opened."
After that, I tried the launcher, and the same message popped up.

I made sure the files were fully downloaded and are complete.
Screenshots can be made available if need be.

Kindly suggest some fixes as I really would like to play on this server.

Thank you,
Vioxe
