Can anyone help me sort this issue? Thanks

Best Answer

The command \bbl@nonfrenchlistspacing has disappeared from babel-french some time between 2007 and 2008.

The only reasonable thing to do is to add

\makeatletter
\let\bbl@nonfrenchlistspacing\relax
\makeatother

before \begin{document} and tell the maintainers of the class that they should update it.
