Jorge,

  Which version of TRNSYS and which version of the TESS Libraries are 
you using? The TRNSYS version can be determined by opening trnsys.ini 
with a text editor. The TESS Libraries version can be determined by 
looking at the filenames of the dlls that are located in the 
..\trnsysXX\UserLib\ReleaseDLLs\ directory.

kind regards,

  David
