Itinerary Designer error when saving - "The xml element {0} could not be found in the xml document

This is quite simple to fix it. When I was working with ESB Tookit 2.1 in beginning days I had this issue and I spent a quite lot of time fix this issue, I did a Install and and uninstall of ESB.

Funny, I even reinstalled of VS2010 too :-) later I found its nothing to do with installation its simple trick , all you have to do is Open your itinerary Properties window and set below properties

Encryption Certificate=My;CurrentUser;
Export Mode = Strict
Required Encryption Certification=False
