I just upgraded from the Lite version to the Premium version. For some reason it wouldn't install, so I deleted the Lite version entirely, and then installed the Premium from the wpmudev dash. It works, except that on the Access Levels, where you should be able to drop in rules, it's not working. And also, the icon is missing in the dashboard (just a ?).
The other issue I have is that the registration form is very...messy? Things aren't aligned, etc.
