Brad,
  There seem to be two different sources of TMY3 data on NREL's site. I 
do not think that this is an issue of the demo version versus the full 
TRNSYS version. I will email you a copy of the Albany TMY3 data that I 
downloaded from NREL's site; it is correctly read by TRNSYS. Thanks for 
bringing this to my attention.
best,
  David
