So I have been banging my head against a brick wall literally all day. I have tried 3 different Latex editors (Texmaker, TeXstudio, and Texworks) all on top of MikTex. I have tried copying code from others as well as writing my own, with some extremely basic examples such as:
\documentclass{article}
\usepackage{lipsum}
\usepackage{biblatex}
\addbibresource{sample.bib}
\begin{document}
\lipsum[1]
\cite{ref:123}
\printbibliography
\end{document}
Where my sample.bib looks like:
@book{ref:123,
author = {456},
title = {855},
year = {2464},
}
and is saved in the same folder as the Tex file. Any suggestions on how to produce a bibliography would be greatly appreciated, I'm new to Latex!!
The latest:
When I BibTex the document I get this:

123in the.texfile,ref:123in the.bibfile). Did you also run LaTeX/Biber/LaTeX? – Joseph Wright May 16 '15 at 19:33biber. You'll get the messages about undefined citation and empty bibliography the first time you LaTeX the file, but also a biblatex warning "Please (re)run Biber on the file ... and rerun LaTeX afterwards". – pst May 16 '15 at 21:04
