After reinstalling Komento, the Komento backend produces 404 errors

I had Komento previously installed on my site and it was running fine, but I uninstalled it because its functionality was doubling up with the EasyDiscuss Content plugin.

However because of the discuss_posts table size problem - which is considerably slowing down my site and causing all sorts of problems - I've decided to reinstall Komento in addition to Easy Discuss and use Komento instead of the Easy Discuss plugin for the Joomla and K2 commenting.

I've downloaded the latest version, but after installing it, i cannot configure it because the Komento backend only produces 404 errors
