Most probably there is a help file included, but still you could ask for the help of the author. You can contact him through the contact form in his profile page. Depending on the category the file was listed, you may need specific software to edit it (After Effects, Apple Motion, Cinema 4d etc). The item description holds this info. Good luck!
