mdframed

salve,

caricando il pacchetto mdframed nel preambolo:

`\documentclass[12pt,a4paper,oneside,openright,titlepage,fleqn,
cleardoubleempty,abstractoff,pointlessnumbers,
headinclude,footinclude,tablecaptionabove]{scrbook}
\usepackage[latin1]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{mathtools}
\usepackage{amsfonts,amssymb,amsthm}
\usepackage[italian]{varioref}
\usepackage[tight,italian]{minitoc}
\usepackage{makeidx}
\usepackage{multicol}
\usepackage{chngpage,calc}

\usepackage{paralist,enumitem}
\usepackage{empheq}
\usepackage{setspace}
\usepackage{cancel}
\usepackage[square,sort&compress]{natbib}
\usepackage{mdframed}`

ricevo il seguente errore:

`1.109 \DeclareListParser*{mdf@dolist}{,
}
?`

da cosa dipende?
