thechamp, your issue is that the link Dropbox provides is an html page with the download link there.
Try visiting your original link and grabbing the direct url from the Download link. WP Clone should be able to use that. It should start with “dl.dropboxusercontent”
An even easier way, long-term, is to put the file into your Public folder in Dropbox. Then you get the direct link without the html page getting in the way.
