I recently updated to AE 2017 and I am able to video preview but not render. And to add insult to injury, I get a loud sheep"BAAAA!" when I push render. What gives?
We are going to need a lot more information if we are going to be able to help you.
Specifically things like your OS, system specs, etc. as normal, but definitely the contents of your composition and your render settings and output module settings.
