## Can't use \spacefactor' in vertical mode

 Greetings, group. A confernece has provided everyone with a template that does not seem to work with my LaTeX installation, not even the example TeX file. When running pdflatex, I get the following for each occurence of citation in the text: ,----[ Quote ] | ! You can't use \spacefactor' in vertical mode. | \@cite ...r \ifx \@tempa \@zero@skip \spacefactor | 1001 \fi \par \ifnum | \spac... | l.124 ...ist of references: Journal~\cite{bulpitt} ---- The corresponding file called cite.sty contains: ,----[ ] | \def\@cite#1#2{\leavevmode | | \@tempskipa\lastskip \edef\@tempa{\the\@tempskipa}\unskip | | \ifnum\lastpenalty=\z@ \penalty\@highpenalty \fi | | \ifx\@tempa\@zero@skip \spacefactor1001 \fi % if no space before, set flag | | \ifnum\spacefactor>\@m \ \else \hskip\@tempskipa \fi | | \citeleft{#1\if@tempswa \citemid #2\fi | | \spacefactor\@m % punctuation in note doesn't affect outside | | }\citeright} | | \edef\@zero@skip{\the\z@skip} ---- I am not too good with raw LaTeX, so could somebody please assist? I have tried many things already, all in vain. Many thanks in advance, Roy
