Composition panel has gone blank/grey
Running AE 2017 on Windows 10, on a computer with 32GB of RAM, so that shouldn't be a problem.
For some reason one of my projects has stopped updating/appearing in my composition panel. It's every single comp in the project, and none are terribly heavy. Fortunately an older version works, but that means any work done since then is gone. Any reason AE would corrupt a project? (The same project has the same results on a Macbook with 8G of RAM.) The playhead is where it's supposed to be, the magnification is good, you can actually see layer outlines in wireframe mode. I've tried purging the cache. It just no longer talks to the composition panel. Any ideas?
