Symantec Antivirus for Linux definition updates always fail ?

Hi People,

I'm using Symantec Live Update Administrator v 2.3.2 to download and push the definitions to Linux servers. In the past months, it seems that it never success in downloading the definition and I wonder if I can delete the items in C:\Program Files\Symantec\LiveUpdate Administrator\clu-prod directory ?

after that how can I force download the full definition update again ?

Thanks
