Okay, thank you, that did work. I set the wpdm_download_link_expiration_limit to 1 in the plock if block.
I would have sworn I tried it with success more than 3 times before, but I must be mistaken since now it only allows 1 time, even if the same user copies the link URL and pastes in a new browser tab.
I can’t expect buyers of my software to register as a user on my site, and I also didn’t want to limit the downloads that 1 person supplying the proper password could download.
I will admit that I got a bit upset here at first, thinking I had purchased a plugin which seemed useless to me. But I am glad you responded with this workaround, and quite promptly I should not hesitate to add.
Thanks.
