Lightbox forwards only

Hi developer,
trying your execelent pop-up. For some reason its only forwarding to the vimeo clips instead of playing in lightbox. A youtube link instead works correctly. Do you have some idea how get a vimeo playing inside our website?

If i have to donate or pay your plugin first let me know.
Thank you in advance
Best Fabian
