Are you seeing the error message:  "There was no endpoint listening at: ....   that could not except the message.  This is often caused by an incorrect address or SOAP Action.  See interexception, if present for more details." when trying to deactivate your Photo Booth Upload License?

This is generally caused by a poor internet connection or no connection at all.  PBU must speak with our server to deactivate the license and cannot do so if your are not connected to the internet.  Reconnect to the internet and you should be able to deactivate successfully.
