I an new to LaTeX.. My question is about the error I get

Package biblatex Error: File '"FILENAME".bbl' not created by biblatex.
\begin{document}.

I have tried to read the guide to biblatex but I cannot find the mistake in my own code.. Anybody has an idea of the problem? I will provide all necessary info if you can help me.
I am trying to add the bibliography, but it seems a quite tough task -.-

Thank you!

This error happens when there is a .bbl file created by BibTeX for a previous version of the document, when biblatex was not loaded.

Since the .bbl file is generated by Biber or BibTeX, you should remove it and run the appropriate program (Biber, if you use the standard setting for biblatex); this operation will generate a new .bbl file according to biblatex wishes.
