I was working on building a pipeline for morningstar data in the quantopian research notebook a few hours ago. Now for some reason none of the cells run, even a simple "import pandas as pd" or "print 2+2" will not run. All I get is the '*' indicating a cell is running, but nothing happens.
I've tried quiting and restarting the notebook many times, and have signed out and back in again. Is there something wrong with my account?
Thank you
