Checking the SMG logs following events can be found:

There is no way to update spam definitons when license has been populated using off-line method as technically it is not intended for anti-spam filtering.
Offline registration should only be done on a system that is not connected to the internet, is not intended for anti-spam filtering, and does not need to download anti-spam rules or software updates.
