The webservice DownloadNFe has been deactivated according to NT 2014.002.v.1.02.
The webservice you should use is:
https://www1.nfe.fazenda.gov.br/NFeDistribuicaoDFe/NFeDistribuicaoDFe.asmx
In this webservice you make the manifestation of the recipient and in the next query it returns the complete NFe XML.
Follow the link of the technical note: Technical Note 2014.002 - v1.02
I made a very simple example, I put a button and a textbox in a form. I added the webservice address in the visual studio project as ServiceReference, so visual studio already generates the necessary classes. Here is the code:
