Failed To import Conversation Script


I have installed I.S 6.0.1, TN 6.0.1 and Modeler 6.0.1. I created a simple model using the modeler. When I import the .xml file generated by the modeler in the TN Console, I get the following error:

File is not a valid IDataXMLCoder file.
Fix File or select another file.

Please help.

XML generated by Modeler
PurchaseOrderRequest1.Design_Server.xml (4.4 k)

PLease help. I am in urgent need.
