Apologies if I'm not using the right etiquette when posting on here, this is my first post.

I have spent hours trying to torrent Melodyne for my Macbook and I feel like i keep falling at the final hurdle. I have used pirate bay and a bit torrent to download Melodyne and I have replaced the files with K'd files which is what I understand you are supposed to do. However, when I try to use/open Melodyne i get the same error message (I have attached a picture of the error message). I am very new to doing this so I would appreciate any help if anyone knows how to fix this or has had the same problem. I can also answer any questions if anyone has any.

Thank you
