No need to copy so many times.<br>
<br>
Could you let use have a `unified.bib' file with, at least, that reference for testing purposes. Did you actually process using biber rather than bibtex as required, by default, biblatex? Also, you don't use \bibliography{unified} with biblatex but rather \addbibresource{unified.bib}
(also note the extension as part of the argument). <br>
<br>
Good Luck,<br>
