The current update for client 4.01.07 is SU10C (NS040107SU10C). You also need G02C (NS040107G002C) assuming you are on a Meridian 1 (if DMS, then it would be NS040107G003C). I believe that G013C is only a document update, and did not address any functionality fixes.
On your Symposium server: If it is at Release 4.2, it should have service update NS040206SU09S. If the server is Release 4.0, it needs to have service update NS040107SU10S.
