Do NOT start downloads via rightclick context menu as this will bypass custom/user limits and start downloads as long as possible (reaching upper limit provided by plugins).
Just hit the start button and JDownloader should download max 2 files from rapidgator and then go over to next possible download/hoster. When you start via rightclick menu, you enforce the download to ignore limits.
Please try that and provide feedback
