Konflikt zwischen Paketen

[nameac]

Hallo zusammen,

wenn ich die folgendes Min.-Bsp. mit Latex (F2) in Texmaker ausführe, erhalte ich die Fehlermeldung:

! No room for a new \dimen .
\ch@ck ...\else \errmessage {No room for a new #3}
\fi
l.59 \newdimen\@belowrulesep
This error message was generated by an \errmessage
command, so I can't give any explicit help.

Was kann man da machen?
