[Plugin: Lightbox Plus ColorBox] Lightbox link not working with shortcode button

I am trying to put a lightbox vimeo video that will popup by clicking on a shortcode button. I am using the theme Simple Key and using one of the shortcode buttons that the theme provides. I am using the following code and have followed all of the regular steps for it to work but when I press the button it opens the video on a separate page!

[button class=”lbpModal cboxElement” rel=”wp-video-lightbox” href=”http://player.vimeo.com/video/39630957″ text=”Teaser” color=”green” size=”large” text-color=”#fff” bg-color=”#” align=”center” target=”_blank”]

I have tried removing the target part of the code but it just opens the video on the same page instead which is even worse!

Can anyone please help me, I am desperate and on a time limit!
