Hey Meseko,
Sorry you've experienced an issue with the extension I haven't had any others report problems with the email validation. For future reference technical support questions should be posted on the developers website. This allows the developer to reply and help get the problem fixed.
With regards to your comment of styling, this is something that is supported. You can disable the CSS that comes with the extension through the component parameters allowing you to customise the styles through your template.
Thanks,
Andy
