Unable to Create a new model

[Theforcemajeure]

Hello,

I downloaded MUIO v5 last week and I am unable to create and configure a new model. I have seen a solution from Vedran Kapoor however, I am not able to implement it. Do I need to have knowledge of Python to correct this problem? Could I get a video, or a brief write up of the solution, step by step? (Pardon my questions - I do not have a computer science background)

Thanks and good day

Regards

David
