You can download a file up to 20 times within a 24-hour period. After reaching this limit, the item will be temporarily blocked, and you won’t be able to download it again for the next 24 hours.
Envato suggests avoiding the use of download managers when downloading your purchased files from Envato Market.
Download managers send multiple requests and open several connections to the server, with each counting as a separate download.
This can cause the server to receive an unusually high number of download requests, which might lead to the item hitting the download limit sooner.
