I don't know if it's the website doing it or if the individual owners block people they don't like for whatever personal agenda or if some outside third party but you have to just download the ones you want and not do collections. It turns out Java I think might have been the problem? But there is no indication that was the issue but it seems to have been fixed. Update: I found out my Java was a long time not updated on a hunch I decided to see if that might fix it which my next step would've been to reinstall Jdownloaer 2. I finally got the file I wanted thru Jdownloader 2 indivdually.
Internet Archive randomly drops connections over 1GB in size and some files don't fully make it. Hence I dropped it a star due to the process involved. IE: The letter H is one such letter with 'Missing files'. Update to the Update: Some letters say 'Missing files' so if I want to I'll have to fish them out manually in the actual archive.
