So i've been monitoring this thread for a while hoping to hear there would be a fix but so far i guess nothing, anyways after trying every download manager possible; jdownloader(obviously) MiPony, Orbit, DAP, FlashGet, DownloadThemAll and even fileserve manager. I finally found some success with IDM for most of yesterday i couldn't download batch links, and later that day i couldn't even download single links with it. But as of early today everything seems to be working well so anyone who wasn't having success with IDM or hand't tried it, you should try it now it might work for you too at least until this issue with JD is fixed.
