Hi, I also having problems with the license, getting notifications of an expired trial, Wrong license ID, etcetera...
But another weird thing that has been happening is that the UI of round corner is incomplete, the background appears, but no info or buttons or icons appears, and there is no way to change the values.
I really hope the server is back up again soon, because I use this extensions everyday. I don't really get why would this extension need to phone home, just to end up broken.
