Our central license server at ephere.com had stopped without a notice. It is back up now, online licensing should work.
In general, to avoid depending on our central license server you can install a license server locally. But you may experience a different kind of problems (like having to reinstall it if your hardware changes).
From now on we'll take better care to keep the LS at ephere.com running.
