Does anyone here use HOT2000?

I am getting this error whenever I try to Calculate/Generate a report for this energy model. I don't have blower door testing as this is a new construction. Under the Natural Air Infiltration section I have tried changing the Air Tightness Type, and even manually entering a blower door test value, and it keeps giving me this error although with different numbers.

I should disclose that this is a 4-storey building, and half of the GF and lower level is a parking garage, and I have modelled the parking garage as an exterior space so the footprint of the 2/F, GF and Lower Level are all different. I wonder if this is tripping the model up?

Any help would be appreciated and thanks.
