[OS X TeX] TeXShop/Latex error

[Kevin Fjelsted]

I am running TeXShop 3.06.
I just ran TeX Live and updated all with no errors.

When I try and convert my document via TypeSet I receive the following error.
<<<
(/usr/local/texlive/2011/texmf-dist/tex/latex/apacite/english.apc
File: english.apc 2012/02/25 v6.01 apacite language file


/usr/local/texlive/2011/texmf-dist/tex/latex/apacite/english.apc:55: LaTeX Erro
r: \onemaskedcitationmsg undefined.

Is the file "english.apc," something that I need to change?
