need help for digital juice Motion Designer's Silhouettes

downloaded 3 volumes from torrent, there are some AE projects in it when I tried to import those files into AFTER EFFECTS it gave error and say cannot import. I change the file extension to .aep but no luck, woul appreciate if someone could help for this

thanks

What is the error you get when you try to import? What was the file extension before you changed it?

file extension is .djae, error message is while trying to import -unsupported file type or extension

thanks
