Trouble Integrating Gallery 2 into Drupal

Hello,
I am working with a fresh install of Gallery 2 and the Gallery plugin for Drupal. On Gallery 2, I have a number of plugins, including the suggested Image Block and Image Frame plugins. On the Drupal side, I have the plugin activated and Gallery Menu activated. When I try to configure the Drupal Gallery Plugin (Site Configuration -> Gallery), it tells me that my location is "Error". Then, when I hit "Test Location Settings" it switches to "The Gallery2 location settings appear to be correct." But when I go to Blocks, the Gallery block is not present. When I return to Site Configuration -> Gallery, I get an error for location once again. What gives?
