Issue with netlisting to PCB Editor

Hi all,

 I am trying to generate a netlist from my schematic to generate the layout for PCB Editor but keep encountering an error which I'm struggling to understand.

 After generating the netlist, the following error log is generated:

 
Loading... c:\sourcesafe working folder\development environment\orcad\triple outlet prompt - 1833\interface\allegro/pstchip.dat

Loading... c:\sourcesafe working folder\development environment\orcad\triple outlet prompt - 1833\interface\allegro/pstchip.dat

Loading... c:\sourcesafe working folder\development environment\orcad\triple outlet prompt - 1833\interface\allegro/pstxprt.dat

Loading... c:\sourcesafe working folder\development environment\orcad\triple outlet prompt - 1833\interface\allegro/pstxnet.dat
ERROR(SPCODD-433):
            Error at line 1603 in file c:\sourcesafe working folder\development environment\orcad\triple outlet prompt - 1833\interface\allegro/pstxnet.dat. Error in syntax.

 Looking t the pstxnet.dat file, specifically at line 1603 where the error is reported, all I see is:

 <snip>

..........

NODE_NAME    CN1 1

END.
 

Line 1603 is the blank line after the END. statement. Not sure what the netlist is falling over on?

Any ideas?
