Insync-headless not starting on Ubuntu 14.04

Hi Insync team -

Insync has been working fine on my ec2 machine (ubuntu 14.04), for a couple of months. I noticed the other day it was not syncing, and saw that it had stopped running. When I do insync-headless start --no-daemon , it appears to start (nothing printed to STDOUT though), then quits back to the command line.

Just bought a pro license, so really hoping this can be figured out. Let me know how I can help. Thanks!
