Decoding of ... Mac OS X 10.4+...was not done because the synchronization failed

I'm getting a error under the Updates section in SEC Manager for my main system.

The details in Update Manager of SEC are: 

11/1/2013 3:00:08PM      80040404      Threat detecion data update failed.

11/1/2013 3:00:06PM      80040410      Data read from the update source for software subscription "Recommended" was invalid (e.g. corrupt or imcomplete).

11/1/2013 2:26:08PM       80040401      Software update failed.

Sophos LogViewer is reporting:
