After the plugin is installed and activated, all legal pages will be created autamatically. We use a really simple Wordpress function to do that so there's literally 0% chance the plugin won't work.
If you think the plugin is not working on your site, just deactivate the plugin then activate it once again. NOTE: Before you deactivating the plugin, make sure you checked Pages -> Trash also. If there were any legal pages there, you need to click the Empty Trash button first. Then you can go deactivate the plugin.
After you do the steps above, visit your Dashboard -> Pages, all legal pages should be re-created there.
