admin configuration download downloading ebook edit entered failed file incorrect later message neither product purchasing received remote remove respond sale seller served server try uploaded upon url

My ebook is not downloading upon purchasing. my first sale could not download it and neither could I. I received the following message:

This file is served directly by the seller. At this moment seller's server has failed to respond. Please try again later.

This is incorrect as the file has been uploaded to e-junkie.

Please go to Admin > Edit product and remove the "remote url" that you have entered in your product configuration.
