Does it show up in the addons list? Does it throw errors for you? Does it not work as intended and/or as you were hoping it to? If there are slash commands for it, do they do anything? Is there a config for it? Did you make sure it's not in standby mode like the author asked another person in the comments when they said that it "didn't work"?
Ask any author if "it doesn't work" is vague or not, and they'll give you a yes.
