BibLateX - Missing \begin{document} [closed]

Question

I wanted to use BibLateX with IEEE style, because of urldate. The problem is, I'm getting error:

! LaTeX Error: Missing \begin{document}.

I'm using pdftex and bibtex for compilation.

I'm completely new to biblatex, so I wrote this code according to the answers in this question.

Edit:

I'm using TexMaker - now with biber option for compilation according to this question.

My code

\documentclass{article}

\usepackage[
backend=biber,
style=ieee
]{biblatex}

\addbibresource{paralel_distribution.bib}

\usepackage{hyperref}

\begin{document}
aaaa

aaaaaaaaaaa \cite{blackford1997scalapack}

aaaaaaaaaaa \cite{balay2014petsc}

\printbibliography
\end{document}
