[texhax] nar style

[Shibin Qiu]

I have problems using nar style (Nucleic Acids Research) 
with my WinEdt and MikTex. When I compile I got errors 
like

"<C:\texmf\tex\latex\base\size12.clo>><art10.sty
!Undefined control sequence, 1.46 \intextsep 12pt plus 2 
pt minus 2 pt \@maxsep 20 pt \dblfoatsep 12 pt plus..."

Can any body tell me why and how to use nar style?

Regards.
