First data global gateway webservice API Integration gives error in asp.net
<p>I have faced a problem on adding the webservice as web reference in vs10 to a project. The Webservice url is "https://ws.merchanttest.firstdataglobalgateway.com/fdggwsapi/services/order.wsdl"
I have installed all the necessary files to my system and iis(windows xp-2003 sp2, X64 version).
When i am trying to add this webservice it displays a blank page "This program cannot display the webpage" not the method lists.</p>

<p>"There was an error downloading 'https://ws.merchanttest.firstdataglobalgateway.com/fdggwsapi/services/order.wsdl'.
The underlying connection was closed: An unexpected error occurred on a receive.
The decryption operation failed, see inner exception.
The message received was unexpected or badly fo"</p>
