Created Unassigned: Import from Facebook group does not appear in NodeXL Data Menu [24349]

Hello,

I have copied FacebookAPI.dll and SocialNetImporter.dll into C:\Program Files\Social Media Research Foundation\NodeXL Excel Template\PlugIns
However, when I start NodeXl, the Facebook import group/page does not appear in the NodeXL>Data>Import menu (even after restarting Windows)

I am using:
- NodeXL Excel Template v1.0.1.238
- Social Network Importer v.1.7
- Excel 2010 over Windows XP.

Best!
Antoinet
