Capatcha problem

[ Moderator note: moved to Fixing WordPress. ]

Hi Guys,

I have installed the captcha plugin on my 2 websites which you can access via http://www.lezioninglese.com but the captcha window does not appear when I select the Union Jack flag (lezioninglese.com/en), so I am unable to log-in as administrator to fix the plugin problem.

It removed it from the Italian side of the site, from the dashboard which I am able to access (lezioninglese.com/it)

The Capatcha version is Version 1.06 | By BestWebSoft

Has Anyone got any ideas?
