I'm using the Ultimate URLs plugin - I'm certain the issue is in the .htaccess file the plugin utilises because the "Not Found" issue goes away when the plugin is deactivated.

The .htaccess file is provided with the plugin and has not been altered / edited but obviously needs to be tweaked - any ideas?
Ok, you should see another .htaccess file called .htaccess. bAK for you ultimate URL copy the whole code inside that then paste it in the .htaccess file under the that original code. Then it should work.
