If you are having problems downloading from Uploaded.net I would suggest using a piece of software called JDownloader. We have used JDownloader several times when we have been on a slow connection or having problems with downloads not completing.
The best thing is of course to buy a premium account at Uploaded.net and enjoy max download speeds! We get 50Mbit+ downloads from them all the time.
Core News has been using many different file hosts throughout the years and it is not possible to find one that everyone is happy with.
If the download should be deleted by the file host or there are other errors, please use the contact form to tell us about it.
