I am getting this at a customer site on a program that has been running without any changes to the program or environment for months, any idea where to start on this one?

XmlException
 Root element is missing.

Source     : System.Xml

Yeah, they corrupted the connection.dat files on their local machine.  We changed the 1.6.1 version to not do in place file conversions, but to correct the issue just remove the connections.dat and the appkeys.dat files on their local machine then go back in.  You will have to re-setup the connection string but you should be good after that.
