What you can do? You could program it to work! The last update (15.1) is not acceptable on my system. My workflow is interrupted and I have to jump back to an older version (14.2). This costs time, money and annoyance. After Effects was(!) quality, stability and reliability. Now it has become a rattle box. Make AE great again!

Using AE since 1995 - on a PowerMacintosh with a dongle.
Now: MacBook PRO OSX10.13.4 - with annoy.
