The dashboard is collecting and displaying data OK however no data is being shown in any of the productivity dashboards
Thanks for getting in touch about this issue. TMG Reporter's Productivity sections rely on Microsoft Forefront TMG's URL Filtering feature, which in-turn relies on an active subscription to Forefront TMG's Web Protection Services.
Your question inspired me to put together a KB article on the subject. I hope this helps!
Please let me know if you have any further issues or questions.
