Envato recommends against the use of download managers to download your purchased files from Envato Market.
Download managers send multiple requests and create multiple connections to the server - each one counting as a download.
The server will receive an abnormally large amount of requests to download the file(s) which may result in the item exceeding the download limit.
A file cannot be downloaded more than 20 times within a 24-hour period. Once you reach this limit your item will be flagged and you will not be able to download the file for a further 24 hours.
