&gt;Dear&nbsp;all,
&gt;
&gt;I&nbsp;am&nbsp;running&nbsp;dos.x.&nbsp;I&nbsp;have&nbsp;succeeded&nbsp;in&nbsp;running&nbsp;it&nbsp;couple&nbsp;of&nbsp;times.&nbsp;But&nbsp;for&nbsp;most&nbsp;of&nbsp;the&nbsp;time,&nbsp;I&nbsp;get&nbsp;the&nbsp;error&nbsp;message:
&gt;&nbsp;&nbsp;&nbsp;%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
&gt;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;task&nbsp;#&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;0
&gt;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;from&nbsp;pp_check_file&nbsp;:&nbsp;error&nbsp;#&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2
&gt;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;file&nbsp;/home/.../PbSedos.save&nbsp;not&nbsp;found
&gt;&nbsp;&nbsp;&nbsp;%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
&gt;
&gt;But&nbsp;I&nbsp;have&nbsp;checked&nbsp;and&nbsp;the&nbsp;folder&nbsp;PbSedos.save&nbsp;is&nbsp;definitely&nbsp;there.&nbsp;I&nbsp;am&nbsp;using&nbsp;the&nbsp;same&nbsp;version&nbsp;of&nbsp;espresso&nbsp;and&nbsp;I&nbsp;don't&nbsp;think&nbsp;version&nbsp;should&nbsp;be&nbsp;a&nbsp;problem.
&gt;
&gt;Sometimes,&nbsp;I&nbsp;get&nbsp;the&nbsp;error&nbsp;message:
&gt;&nbsp;%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
&gt;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;from&nbsp;dos&nbsp;:&nbsp;error&nbsp;#&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1
&gt;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;pools&nbsp;not&nbsp;implemented,&nbsp;or&nbsp;incorrect&nbsp;file&nbsp;read
&gt;&nbsp;%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
&gt;
&gt;Or
&gt;%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
&gt;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;reading&nbsp;inputpp&nbsp;namelist
&gt;&nbsp;%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
&gt;
&gt;
&gt;Anyone&nbsp;could&nbsp;give&nbsp;me&nbsp;some&nbsp;hints?
&gt;
&gt;Thanks,
