Error Generating Netlist ( Allegro Version 15.2 )

Hello,

I am getting a error while generating netlist.Can anyone tell me what this error message means ?

Please note that, at first I was using a part in Capture Library which I modified and then I used it in the design. At that time , I was getting the below mentioned error while generating netlist. But when I generated a totally new part in capture  library and used it in my design ,  I was able to generate netlist without any error.

Can anyone help in this matter ...

Design Name:
e:\orcad\allegro\design-ge.dsn
Netlist Directory:
e:\orcad\allegro\allegro
Configuration File:
e:\orcad\allegro\signoise.runcases.cfg,1
