Event Registration Info Formatting/Editing Question

I am trying to use a third-party registration site to register attendees for an Adobe Connect event.  With the "Event Login" block in the event templates, it populates a hyperlink that redirects attendees to the native Adobe Registration page.  See below:

Is there a way to remove that link or replace it with a different URL?  Alternatively, is there a way to delete that whole sentence from the login page?

Thanks
