Hi there,
Technically this isn’t covered by our support, so we can’t really assist much further as it has nothing to do with the theme.
From the looks of the documentation, they suggest trying this format:
<a ONCLICK="VSCapture('page-name-here')" TARGET="new" href="http://www.domain.com/file.pdf"> My PDF Download </a>
Although WordPress may not like the on click parameter, and thus strip it out. I checked Google for any WordPress implementation recommendations, but doesn’t seem like there are any unfortunately.
