I don't have what to add, Jochem already listed all recommended actions. Please let us know if you were able to resolve the issue.
Jochem is absolutely correct. Our standard license does not have the eCommerce, Load balancing and Mobile extensions. They are available as add-ons to your current Sitefinity license.
For your convenience please review the Full Feature List.
We got the license and applied it across our different registered sub domains for dev and testing. It is working in 4 of the 8. The licensing looks the same in all of them, so don't have any idea why it would be working for some, but not all.
Never mind...Just needed to force SiteFinity to re-initialize the Responsive Design model like Jochem suggested near the top of this chain. It was just odd that half of them were working and the other half weren't when I didn't do anything different between the two sets of environments.
Back again...Now that I'm trying to deploy our brand new responsive site, I can't create responsive group rules in my production site. It goes off to do the waiting animation and never comes back to let me enter information in for the group.
I've even gone through the deactivate/uninstall/install dance and nothing different. Everything installs perfectly and the link for responsive & mobile design comes back just like what you would expect, but can't create a group rule no matter what I do.
