Ricrest:
The panes list loaded and available lists. You do not need to copy/paste anything into them.
The proper location for dropping lists is located at
C:\Users\[user]\AppData\Roaming\fireBwall\modules\IPGuard.
Once you restart fireBwall, the list should show up in the righthand side pane. Select the list you'd like to load, and click 'Add List'. This will parse and load the given list.
