Amr,
Thank you for your quick answer.
When running GenOpt, four folders are created named "tmp-genopt-run-1 / 2 / 3 / 4", into each one, there is a log file (here below).
As you can see, there is no error message in the log file, what i have attached at first time was the pop message of the error.
Ines.
