In the upper right hand corner of the console there is a link "LiveUpdate"
This will automatically update to the latest version 2.1.3
There could be several reasons you are not seeing updates.
1) In Configure > My Symantec Products make sure you have selected the products you want updates for and added them to "My Symatnec Products"
2) In Configure > Distribution Centers make sure that you have selected a or created a Distribution Center and configured in this Distribution Center to use the same list of products or a subset of those in "My Symantec Products"
3) In Download & Distribute > Schedules when creating both the Download and Distribution schedule events, make sure that you configure to use the same product list
I hope this helps
