[Plugin: Cool Video Gallery] Pop up window empty

Hi
I correctly inserted [cvg-gallery galleryId=’gid’ /], but when clicking the thumbnails the pop up window does not show any video. The embedded version works, but neither does the showcase and slideshow nor the single video pop up version.
Appreciate your help–thanks.
