[biblio] TeXworks failing to recognize bib file

Thu May 7 06:17:27 CEST 2015

Hi,

I've presently got this TeX (.tex) file:

|\documentclass[a4paper,landscape,12pt,arial]{article}|||

|\usepackage{amsmath}|

||

|\usepackage{chemfig}|

||

|\usepackage[a4paper,landscape]{geometry}|

||

|\usepackage[american]{babel}|

||

|\usepackage{csquotes}|

||

|\usepackage[style=apa]{biblatex}|

||

|\DeclareLanguageMapping{american}{american-apa}|

||

|\usepackage{biblatex}|

||

|\title{\LaTeX}|

||

|\date{7 May 2015}|

||

|\addbibresource{Chem.bib}|

||

|\begin{document}|

||

|\maketitle|

||

||

||

|% This is a comment, not shown in final output.|

||

|% The following shows typesetting power of LaTeX:|

||

|
|

||

|{\chemname{\chemfig{({R_{1}}-[:30]C(=[:90]O)-[:-30]OH)}}{Carboxylic acid}|

||

|\chemsign{+}|

||

|\chemname{\chemfig{{R_{2}}-[:30]N(-[:90]H)-[:-30]{R_{3}}}}{Amine}|

||

|\chemrel{<>}|

||

|\chemname{\chemfig{({R_{1}}-[:30]C(=[:90]O)-[:-30]N(-[:30]{R_{2}})-[:-90]{R_{3}})}}{Carboxamide}|

||

|\chemsign{+}|

||

|\chemname{\chemfig{H_{2} O}}{Water}|

||

|
|

||

|\begin{itemize}|

||

|\item \cite{9780321767257}|

||

|\end{itemize}|

||

||

||

|\printbibliography|

||

|\end{document}|

where Chem.bib is in the same folder as this tex file, and has these 
contents:
|@Book{9780321767257,|||

|author = {McMurry, JE; Ballantine, DS; Hoeger, CA; Peterson, VE},|

||

|title = {Fundamentals of General Organic & Biological Chemistry},|

||

|publisher = {Prentice Hall},|

||

|year = {2012},|

||

|edition = {7th},|

||

|month = {February},|

||

|isbn = 9780321767257|

||

|}|

yet whenever I compile using pdfLaTeX+MakeIndex+BibTeX I get the 
following error:
