Hi. So I have a strange problem. I have a download that consists of 5 part rar file. When I star the download, jdown starts downloading only one file and not even force download will start downloading another part. But I can start downloading another part if I launch another instance of jdownloader. So now I have 5 instances launched and they all download different parts of the rar just fine. Why can't I start downloading in the same instance when clearly the server supports it? Thanks!
