Hello, Hazel:
I'm afraid I don't know the answer to that. If Marc doesn't know, either (he reads these questions, too), then the best way to find out is to post your question at http://socialnetimporter.codeplex.com/discussions. That's the home of the group that created the Facebook importer. (The importer is actually a "plug-in", and not part of NodeXL itself.)
