WPMU DEV SEO wordpress 3.2.1 multisite - Can't see the new menu on per blog

Hi all,

Having a problem with the installation of this pluging.

I just installed from Network Admin -> Plugins and then, Network Activate. After that, on Network Admin I can see the new menu WPMU DEV SEO under Setting and setu up some configuration options. However, I can't see any trace of the pluging when switch to a blog dashboard (the pluging is not listed on blogs->plugings and there is not the WPMU DEV SEO menu under settings.)

Please advice,

Environment: Wordpress 3.2.1 mutisite enabled
Active Plugins: WPMU Google Analytics, WP-ecommerce, domain-mapping
