"too many values to unpack" error with Part 6 of the Honeybee video tutorials

Hi Mostapha and Chris and everyone,

I've run into a rather basic problem I fear while going through Chris' great youtube tutorials for Honeybee. When trying to run E+ through tutorial 6, even with the file directly downloaded from dropbox, I run into a "1. Solution exception:too many values to unpack" when I change the toggle from 'False' to 'True' for the Energy Simulation. 

To try to fix it, I've downloaded the most up to date Ladybug + Honeybee versions from github, and then dragged those into Grasshopper. I've also dragged the icons from the panel onto the sheet. I tried changing the timestep to 'monthly' (in the video, it's 'hourly') but I still get the same error. 

Thanks for any insight!
