Temperature limits of various ECO2N versions

Hi Folks,

Anybody can send me a few words on this:

We have a version of ECO2N (as a part of iTough2.7.0.) which doesn't perform with T>103.4, same indication seen in CO2Tab data that is limited to this temperature and the ECO2N fortran file (SUBROUTINE EOSDATA_17) that seems to have formulated a warning at a temperature beyond 110 deg C. There is absence of so-called ver.file following the license, so to declear the version. 

But still, I can see very small differences in results for phase saturations and phase partitioning when an identical run considered with 2 alternatives of the so-called switch key IE(16)=0 and  IE(16)=1 where there is an opportunity to distinguish between various Spycher and Pruess approaches. You may get an impression that there is different version of ver.1.??

Any similar observations, comment or clarifications are welcomed.

Thanks.
