After Effects previews and composition screens blank
Hello all,
I've scoured the forums trying to find an answer and so far, every solution I've discovered has not been fruitful.
I recently upgraded all of my apps to CC 2017. After Effects and Premiere are both having issues when closing a file. My biggest issue right now is that After Effects composition screens are blank, or showing bounding boxes of something. Playing a scene (either hitting space bar or clicking the play button) toggles the play button, but the time line marker does not move.
I'm working on a file that was converted after the upgrade.
I've manually reset the Preferences and checked all of the display options to be correct.
How can I fix this?
