Yes, it seems OK. Now let's clarify if the basic settings are correct: First, did you really pass the option backend=biber to biblatex? Then, please tell us how you set up biber. Did you specify any options or just select biber from the dropdown list? Also, posting the whole LaTeX log file might shed some light on things. Jürgen
