Why do I keep getting an error when I try to replace my HVAC system with a DOAS with radiant slab system using the NZEHVAC openstudio measure?

edit

I am using Openstudio Application version 1.3.1. When I try to replace my existing HVAC with a DOAS with radiant slab HVAC system using the NZEHVAC measure I keep getting this error: "Error: Unable to perform sizing run for hvac system DOAS with radiant slab air-cooled chiller with boiler for this model. Check the openstudio-standards.log in this measure for more details." Can someone please help me fix this error? This is the only HVAC system that generates an error when I try to use the NZEHVAC measure. I don't have problems replacing my HVAC with all the other HVAC system options of the NZEHVAC measure.
