Ran into issues with UDLicense and the Adminmode stuff as well in my test lab this morning. Since we are still in beta, I wouldn’t be surprised if they just haven’t gotten those bits done yet. I just wrote around to bypass in the lab and continue my other testing.
EDIT: take it back, it is a bit of an issue with the license in my lab, since i access through a front end name/binding on IIS and not localhost.
