Hi Jared,
Thanks for reporting your issue. Can you please check your Tickstory proxy settings by going to File->Settings->Dukascopy Data Source and tell us whether you have any proxy information set? If not, could you please go to Windows->Control Panel->Internet Options->Connections->LAN Settings and tell us whether you have any proxy settings set and what they are? Specifically, it seems that there is a server name specification that seems to be causing the issue.
Does the application resume if you close the error box?
Thanks.
