Parameter Estimation

I am trying to perform a simple parameter estimation but, when I run the followed message appears:
"Module CI, Segment PE01 not found"
what does it means?

Forums: 

It means the executable is missing. My guess is you did not do a complete install of DIANA.

Ok this problem was solved.
But now the followed errors occurs:
 /DIANA/AP/IN51    10:31:28      0.08-CPU     0.22-IO      148-FA   BEGIN

Dears,
Do you have any example about the application of parameter estimation?
