Honeybee Daylight Analysis: Runtime Error Python Exception

Hello,
I’m new to Grasshopper and Honeybee/Ladybug and I’m trying to run some very basic daylight analyses to help design the windows for my studio project. I downloaded and used the Grid-Based Daylight Simulation Example 2, but I’m getting 'Runtime Error (Python Exception): Failed to read results Traceback line 331 in script. I don’t know python so I haven’t been able to check the script.

Thank you in advance for any guidance!!
