Hi Erwin,

Please verify the path to the Name Mapping file. Also, you can try removing the NameMapping
scheme from your project and adding it anew as an existing item (see the "Adding and Removing
Project Items and Their Child Elements" help topic). 

If the suggestions above do not help, please send us the problematic .tcNM file via the following
web form:
