How does "Download Later" work?

I have to d/l a bunch of BIG update files. I clicked "download later" expecting that ANTDM would store the URLs and I'd be able to just start them later, one at a time. The first one finished and now I can't find any sign of the rest in ANTDM. The s/w website seems to be blocking me from trying again because, well, I don't know, it just is. Can you assist me please. AntDM v1.7.11

Hi!
"Download Later" works like you wrote for static links  but not for dynamic ones (links that have a deadline). For example, most video links have a time limit. I think it was your case.
If the lifetime of the link expired, the software will not be able to download it. There is often a HTTP403, HTTP404,... error
