[Plugin: Exclusive Content Password Protect] Adding HTML to blocked content preview

I got the plugin to work just fine. But I would like to add a link to get the password by joining the newsletter (the point after all) in the footnote text area. But I am unable to add a link – it cuts off the code. Is there a solution for this? Thanks ahead of time for your help.
