Feed Burner Subscribe to Download not Working

Hi,

I install CTA plugin on my blog http://pixel2pixeldesign.com and created few call to action button for Feed Burner Subscribe to Download button you can find this button on this post at the bottom of the page http://pixel2pixeldesign.com/freebie-flat-design-ui-kit-psd-enes-dan/

But it is not working when i click on Subscribe via Email button it is redirecting me to the same page and nothing is happening.

Also the button look and feel is an issue on firefox browser also on google crome.

Any help is appreciated.

Thanks & Regards,
Suresh Patel
