COM thermo_Python UO in Aspen Hysys V11

[Emanuela]

Hello,
I have a problem in the implementation of the Python Unit Operation in Aspen Hysys V11. In particular when setting the COM thermo property package, and selecting the CAPE-OPEN 1.1 for the vapor and for the liquid, the following error occurs (FIG_error) independently from the selection (Default, Hcgas or Simple). Does anyone know what I’m doing wrong?
Thank you in advance

The message "something is wrong" is very vague. Default.cota is a pre-installed package, or did you export that from a working simulation?
