It took me quite a while to figure this out, so I thought maybe this could be useful to someone else.

My disk filled up why JDownloader was working, so it aborted all downloads. I made some space, and could restart some downloads after that. But most of the remaining links to downloaded were disabled (greyed out). By right-clicking on them, I got the contextual (popup) menu, with all the options, including "enable" which is what I had to use (I found this answer on the forums somewhere). However, I was seeing only "enable (0)" in the menu and of course it wasn't doing anything.

After a lot of tries, I selected several links, and *bam* the contextual menu changed. So you have typically to select the container (is that the right name?) and all the links you want to enable, then the menu works perfectly.

Sorry if everyone already knew this trick...
