mcerro on "[Plugin: OSE Firewall™ Security] Dashboard error"

I have installed the plugin (2.2.6) and the dashboard doesn't show properly. I checked it whit firebug and it doesn't show any errors or missing stylesheets, but i can't install the database because there isn't any button to install it. Please check the screen, thanks
