Alessandro,
   If you can email the *.b17 file, it is a bit easier to tell what the 
problem may be. If I had to guess, I would say that one of your walls is 
either too massive or not massive enough for TRNBuild to generate 
transfer function coefficients. To determine which wall is causing the 
problem, look in the *.inf file (it is text based). If it is a very low 
thermal mass wall, you can treat it as a purely resistive wall (i.e. 
treat it as though it had no thermal mass by using "massless" layers 
only.) If it is a very thick or highly thermally massive wall, you can 
increase the timebase to 2 hours (click on the outputs button in the 
main project window).
Kind regards,
  David
