Hi, reesej19.
The issue of the Content Rotator element not being visible in Visual Composer was fixed in the 1.1 theme update.
The current version of the theme is 1.1.2: http://para.llel.us/support/groups/incentive/forum/topic/latest-version-incentive/
If you are up to date with the theme and you still don’t see the Content Rotator element then go to Settings > Visual Composer > General Settings and make sure that the element is enabled in the User groups access rules for Administrator.
With regard to your question about content rotator and lightboxes, please see the following post:
