We just released a new WatchFTP version, the download is available on our download page. This is a free update for all customers, just install it "on top" of your current version.
New in this release
This release fixes an issue where (some) FTP servers do not send a "succes" reply after a very large download. Previous WatchFTP releases interpreted this as a download faillure and downloaded the file again. This new release first checks if the file has been downloaded properly.
