How do I find the primary links config? I'm running Drupal 7, and I am using the Acquia Marina theme. I am having issues with the drop-down menu (using superfish). The menu items with children simply remain expanded.

Every tutorial and user post I've looked at, the Primary Link Configuration table always comes up. 



I cannot find this screen, anywhere. Can anybody help me?
You can get to that screen via the 'Administration' page, which you'll find at yourdrupalroot/admin . You'll need to drill down through the subpages there differently depending on your Drupal version; in Drupal 7 it will be under Structure > Menus > Main menu (the renamed version of 'Primary links').
