I have "some" problems with LyX and BibLaTeX. I have to admit that I am a newbie and it is possible I have done some basic errors in my LyX document or in this message

I have followed the points showed in the corresponding section of the LyX Wiki, but it does not work at all.
- I have put the file biblatex.module in the layouts folder
- I have run Tools -> Reconfigure, restart LyX and I have selected the module "Biblatex-citation-styles" from Document→Settings→Modules
- I have written \usepackage[style=authoryear,natbib=true]{biblatex} in the preamble
- In the preamble I have also written \bibliography{<C:/Documents and Settings/User/Desktop/TESI_ILARIA_FORMAT/biblioprova>} with the normal slash (/) instead of the backslash (\) because I am in Windows.
- I have inserted the bibliography in a LyX note at the beginning of the document
- I have put two citation in the text and, at the end, I have put the command \printbibliography in ERT
I attach the LyX text, the preamble, the Bibliography file and the PDF.
LYX text:
PREAMBLE:Title [bibliography in lix note]
1 Chapter 1
BlaBlaBlaMichel (2001)(It is the first citation)
Bla Bla Bla
2 Chapter 2

(\printbibliography in ERT)
Code: Select all
\usepackage[style=authoryear,natbib=true]{biblatex}\bibliography{<C:/Documents and Settings/User/Desktop/TESI_ILARIA_FORMAT/biblioprova>}
Code: Select all
@book{critica,author = {Michel, Foucault},title = {Qu'est-ce que la critique?},publisher = {Sylvestre Bonnard},year = {2001},location = {Milano}}@ARTICLE{JonesRadclifTabor1995,author = {Bradford Jones and Benjamin Radcliffe and Charles Taber and Richard Timpone},title = {Condorcet Winners and the Paradox of Voting},journal = {American Political Science Review},year = {1995},volume = {89},number = {1},pages = {137-144},owner = {pauljohn},}
As you can see there are no books and the citations are not true citations but they are only the keys in bold.Title
