Mattia, From the error message it appears as though there is a problem with the *.trn file. This file is generated by TRNBuild and contains the transfer function coefficients for the walls, floors, ceilings, and roofs of your Type56 building. I would recommend that you open your building (*.bui, or *.b17) and resave it to make sure that there is not an error saying that some of the wall transfer function coefficients could not be generated. If you are able to save the building file from TRNBuild and the simulation still will not run, please send the *.b17 and *.tpf to your distributor for assistance.
