Hello. We need help in solving one problem, on the Joomla version 3.9.4 site, the jDownloads Version 220.127.116.11 component is installed in conjunction with AltaUserPoints 1.1.13, the rules for buying and selling files for points are included.
So you need a plugin or revision so that you can set the parameter for the downloaded file - how many times you can download it this: only 1 time (and immediately remove it from publication automatically) or many times (as the system initially set by default).
What is the point - to buy for points will be unique codes, and this can not be done when the file can be downloaded many times, that's why you need a plugin that can set only 1 download and remove the file from publication immediately after downloading, then for further updates(downloading a new unique code) and selling again only 1 time, etc.
I hope I explained it clearly...
