Symantec Mail Security for Microsoft Exchange does not update virus definitions

I have a windows 2003 server with SMSME 6.5.7.279. The problem is that the virus definitions seem to be stuck at 8/15/2013. when i try to manually run the liveupdate certified definitions, i receive  message that states

liveupdate has determined that no update is necessary. you already have the most recent virus definitions

Below are the logs from log.liveupdate file.

Any idea what can be going on? I already uninstalled(rebooted) and installed the application and it still does not update. I also have a sym endpoint protection client installed showing a yellow exclamation mark. But I am not sure if this is relevant.
