Hi Ticker,
This error usually occurs when there is some fault with your internet connection (eg. disconnection, too many simultaneous requests, etc). Just make sure your settings are correct by firstly going to File->Settings and ‘Test’ your Dukascopy settings. If all is ok, the next step is to use the ‘Download’ function to re-check all the existing data in your local database. The system will go through the specified date range again and only download the data that may be missing. If you still receive errors, please review them and again ensure your internet connection is working before repeating the above.
Regards.
