Content acquisition method, content acquisition device, and content acquisition program

The present invention allows for the acquisition of content data. The present invention temporarily stores the first and second process progress information in the storage medium, and, when the requested content data and license data are registered in the database after being downloaded and temporarily stored in the storage medium, removes the first and second process progress information, and, if there are the first and/or second process progress information are left when the stopped content acquisition process restarts, retries to acquire data after removing the content data and license data corresponding to the second process progress information. This prevents, when the data acquisition is retried, the same content data and license data from being stored in the storage medium again. This allows efficient use of the storage space, and therefore the content data is acquired without fail.
