A couple questions if you have a minute: 1. Did you load the example scenario and run that? 2. If not, try checking that the fields in the Market & Portfolio tab are all filled out, or set it to "Automatic Weights". I see a few errors relating to validation on that page, so that seems like the most likely culprit. I'll work on some better messaging for that particular error as well. In the meantime, I've updated the defaults to use the automatic weights, so that should be less common for new users.
