Thanks for the help. I forgot to mention that I am on Mac 10.11.5. I have update the software for OS to the latest. I also rest AE preference as you taught. However, my AE still crashed.
You could revert to AE 2015.1 until a further update is brought out.
I'm continuing to use 2014, as it seems the most stable.
Awseom! This does solved the problem! AE doesn't crash anymore. I guess I won't click any "update" button anymore. I will just stick with the version I have.
Thanks for your help!
