Free Memberships - Set Expired Member to Active

See here:
http://screencast.com/t/mcnamadpbxiP

We have some users, we want to manually set to Active, and give a free membership. When we set to Active, and click save, it fails, and sets the user back to Expired?

How do we manually set a few special users to Free membership?

Support access is ACTIVE until 2015-12-20 8:35 pm
