your files need to be inside a .RAR or .ZIP archive before they can be attached to a post.. and the media fire link you posted has no files in it.. its empty.
if you cant edit your post and add the attachment, you can upload the .RAR or .ZIP archive of the files to Media Fire and PM the download link to me for approval.. i'll add it to your post and fix it for you
google WinRAR if you dont already have it.
