Ladybug update error

I installed ladybug tools on a fresh machine.
The fresh install was with ladybug v1.6.0 from food4rhino installer.
Getting this error now after updating from 1.6.0 to 1.6.8

Any help is appreciated. Thanks!

After reverting back to 1.6.0, I tried to load one of my honeybee models that was baked from a different machine. I am getting this error now

The model loads and works fine with all my scripts on my primary machine. I am trying to setup an additional machine so I can run more simulations.
