Need to configure Global Document Storage

Hi,

I need to chang the location of my Global Document storage to some common network drive. Online Docs say I need to go to Livecycle Admin Console and then navigate to Setting ->Core System Settings ->Configurations and then change the GDS
But the problem is when I log into the admin console->Settings I get no link for Core System Settings. I guess this might be a problem with the livecycle version I am using but can't be sure. Anyways, does anyone know whethet I could modify the location directly by changing some attribute in a config file or something?

Thanks
S.
