We're aware of an issue with the Roamio with the grace period functionality.
Normally, a unit that hasn't been activated yet has a grace period of service. However, we're seeing a bug for Roamio units.
If you set up a Roamio unit and complete Guided Setup, if you're seeing the box in a deactivated state, please wait one hour, then force a connection to the TiVo service. (http://support.tivo.com/app/answers/detail/a_id/395
At that point, grace period functionality will work normally.
We are investigating the bug and working to correct it. But in the meantime, the workaround listed here will need to be employed (or you can just activate service by visiting http://tivo.com/activate/
We apologize for the problem.
