Imported transitions not working

Try updating or rolling back your graphics driver directly from the video card manufacturer’s site.

If that doesn’t work, you may need to contact the transition pack vendor.

You need to render the timeline by pressing enter so that the red line above the timeline turns green.

Your computer is not powerful enough to play the timeline in real time without rendering it.

With the timeline window selected, (as is, in the screenshot) select SEQUENCE\Sequence Settings, you can post that screen if you like.

Most of the tranisitions I've seen similar to yours have more than one track of info, did you try a few different effects?

I'd read the instructions for the transitions again.  Those can be finicky.  Make sure the project settings match: use 1080 transitions in a 1080 project, etc.
