Using DS212j with DSM 4.0 and the respective Download Station package.
After Download Station completes the newsgroup NZB download and the files have been moved to user/downloads directory automatically, all the downloaded files are 0kb. It's the same with a few different NZB's. During the download, Download Station screen shows proper download speeds and progress but after it completes, all I get are 0 byte files.
All was working fine when using DSM 3.2 before the upgrade. HTTP downloads are also working fine now. Only NZB newsgroup downloads gives empty files.
