Using biblatex - having trouble getting it all working

Question

I've been trying to get it all setup for a while but though the errors have stopped I can't actually get any references working.

Here's the references file :

 32 @book{wrong,
 33         author          = {Mr Writer},
 34         title           = {My First Novel},
 35         year            = {2012}, 
 36         publisher       = {Harold & Mike},
 37         location        ] {London
 38 }

Here's how the reference displays in text (wrongii was a different reference):

}

Here's the code from the text that's calling the reference :

  I'm trying a different way with this line \parencite{wrong}

I've also tried to print this Bibliography at the bottom of the page to no effect using :

\printbibliography

I've been rattling about various sites (including here) and can't seem to find the answer, any help much appreciated.

EDIT

This is my MWE that seems to display the same behaviour :

\documentclass[10pt,a4paper]{book}
\usepackage[style=authoryear]{biblatex}
\bibliography{mwe.bib}

\begin{document}
This is some text that I'm going to try and 'cite' using the bib file thing.\cite{wrong}

That didn't work, maybe this will \parencite{wrong}

\printbibliography
\end{document}

And here's the contents of the references.bib file :

  1 @book{wrong,
  2         author          = {Mr Writer},
  3         title           = {My First Novel},
  4         year            = {2012},
  5         publisher       = {Harold \& Mike},
  6         location        = {Leamingtion}
  7 }

~                                                                                                                                                                                                                                              
~                                        

I'm not sure if this is a Texmate setting, I've read things about the backend = bibtex setting and tried that too (it didn't work). I want to have it in author year style, but to start I guess it'd be nice to just have something on there

Options within Texmaker for compiling :

This seems to have worked :

Here's the error message that I'm currently getting :

Apparently I'm meant to use nocite{} ?

Sorry this post is ridiculously convoluted :(
